Navigation could be described as controlling and operating the movement of a craft from one location to another. We can, therefore, distinguish many types of navigation: marine, air, military and even one used in the oil and gas industry.

It is a study dating back to the earliest human civilisations, with the ancient travellers relying on the position of the stars and hand-drawn maps. Indeed, the instruments of navigation have always been a crucial part of the process, as they allowed for the highest possible precision and proper displacement of a vehicle or a craft. Unfortunately, the star position-based estimations and, later, analogue tools such as compasses and astrolabes, used back in the day were not enough to provide utmost precision. That has evolved with the age of technology. Nowadays, numerical devices and instruments are employed within the different sectors of this study, largely improving the exactness and pinpointing of the vehicles’ location and, hence, aiding the navigators in their paths.

So, what are some technologies and systems put in place to ensure the proper functioning of all of these various operations?

Satellite-based systems

You have probably guessed it, the modern-day navigation relies largely on the Global Navigation Satellite systems (GNSS), such as your global positioning system. You may know it as, simply, GPS.  As we’ve said previously, in aviation precision is of the highest importance and so the GNSS are alimented by what we call “augmentation systems”. There are three types: ground-bases, satellite-based (SBAS) and aircraft-based augmentation systems.  The International Civil Aviation Organisation (ICAO) prescribes these to improve the performance-based navigation. For instance, SBAS, supports wide-area and regional augmentation of information.

Radio frequency-based solutions 

Once within the range of the aerodrome, the airplane is guided by many other tools.

Firstly, we have instrument landing systems (ILS). This infrastructure’s functioning is based on radio frequency emission and is implemented in short-range guidance for the planes as they approach a runway in obscure weather conditions, such as in rain, at dusk or at night-time. This is a critical safety measure, used along with the airport lighting to help pilots determine the exact position of the runways. An example of ILS, which you may recognise is the glide path localiser. Another radio frequency-based equipment used in aviation is one that measures the distance between the airplane and the ground station (DME). It is used during landing and en-route.

Aircraft also use Doppler VHF omnidirectional range (DVOR), which operates over a short to medium-range distance in order to determine the flight’s bearing and aid it during approach to the aerodrome. As their name suggests, DVORS send omnidirectional radio signals to the receiving units that could identify the crafts’ exact positions, helping them maintain travel in the right direction.

Interestingly, in military, we see the use of TACAN or tactical air navigation. This is a more precise version of the above-mentioned VOR and DME systems.

We also have non-directional radio beacons, which are not only used in aviation but also, in marine navigation. Unlike the other discussed systems, these operate over a longer range and lower altitudes, as they follow the curvature of the Earth. This also implies that these signals are affected by geographical factors such terrain types, weather and atmospheric conditions.  Following the touchdown, an aircraft needs to be guided to the parking area. Advanced Visual Docking Guidance System (A-VDGC) is an essential solution that provides pilots with information necessary for and smooth travelling across the aerodrome grounds, avoiding potential obstacles on taxiways and leading the plane straight to the jetways.

The modern navigation tools vary in their purposes and functioning, and multiply as world travelling grows. The solutions presented are only a fraction of the existing instruments that help guide pilots and their craft, ensuring safety and precision throughout the journey. Bayanat engineering specialises in civil and military aviation solutions, as well as in those related to marine and oil and gas navigation.

Bayanat Engineering: Airport surveillance and security

Airports, the international hubs of the world, oversee the passage of millions of visitors every year. With large crowds constantly circulating, it is essential to ensure not only their safety, but that of the entire airport, maintaining its proper and lawful functioning. It is also important to prevent any potential threat from entering the country.

And so, there is a plethora of techniques put in place to ensure security of the passengers, staff, equipment, vehicles and aircraft at any given location of the facility.

Security and surveillance equipment is most commonly used to observe the traffic in the monitored zone, including potential animals, vehicles or people on the site. It also detects unfavourable meteorological conditions or other aircraft in sight of the runway. These infrastructures operate both at daytime and at night, the latter being a more risky period in terms of potential threats due to lower visibility.

The Surface Movement Guidance and Control System

It is important to know that the airports are equipped with a special surveillance system, called the Surface Movement Guidance and Control System (ASMGCS). This includes a variety of different devices and infrastructure.

More generally, these could be separated into two parts: non-cooperative surveillance (Surface movement radars, microwave sensors), and cooperative surveillance, among which, you could find the Multilateration system.
According to the International Civil Aviation Organisation (ICAO), the ASMGCS maintains the rate of all vehicles’ and aircraft’s movement on the surface of the aerodrome, by providing these with routing, guidance and surveillance. It declares the surface movement rate in any given weather conditions that enter into the aerodrome visibility operational level. Finally, it also assures safety requirements are met.

Different types of radars

Based on this, you can imagine that the infrastructure consists of various important components. We have already mentioned the Surface Movement radars (SMR, GMR), these are used by surface traffic controllers to detect aircraft and vehicles on the airport grounds, during the day, the night, at dusk, dawn and, more generally, in low visibility conditions. This very precise equipment is designed to provide callsigns that identify the target, as well as send warnings in case of a potential danger.

But this isn’t quite the end of the radar use in aviation. The spectre of these devices is huge, and each type contributes its specific role to the surveillance and safety of the airport and aircrafts. For instance, the primary surveillance radar (PSR), the only one that does not require any specific equipment on board of the aircraft, uses reflected radio waves to determine the latter’s coordinates and direction. The aircraft receives the radio signal from the radar and emits it back to the PSR’s antenna.

However, the primary radar, apart from determining an object’s position, is unable to identify the exact target. This is where the secondary radar comes into play.

Another component of the ASMGCS that we’ve addressed are the multilareration systems (MLAT), which are a part of the cooperative surveillance. As with the radars, the accuracy of the multilateration systems is a crucial aspect of their functioning. They provide information on the vehicle’s position to its exterior recipients, i.e., to the air traffic controller.

Detecting objects outside the aircraft

Automatic Dependent Surveillance technologies (ADS-B/TIS-B), reliant on the satellite navigation, are used by an aircraft to determine its exact position, so that it is broadcast and tracked. Not only does the airport staff depend on this information, but other airplanes in the area also need to be aware of each other’s positions, in order to avoid accidents and, hence, contributes to air navigation safety.

But it isn’t only airplanes that could get in the way of their winged homologues. On the ground, what is referred to as the runway foreign objects debris (FOD), constitutes any objects fallen from the aircraft, broken ground equipment or even birds. To maintain the overall safety of the aerodrome, many other types of surveillance are put in place for runways and airside. These and many other aviation solutions are provided by the engineering companies such as Bayanat Engineering, the latter being a leader in its sector in the Middle East. The company provides surveillance and security systems, along with many other solutions to large international airports including Hamad International Airport.

Bayanat Engineering Qatar: Supplying with extra-low voltage and current systems  

Bayanat Engineering Qatar: Supplying with extra-low voltage and current systems

Nowadays, we see more and more enterprises invest in extra-low voltage (ELV) and current systems. These systems are energy and cost efficient and implementing them into what is called a “smart building” promotes both sustainability and interconnectivity within the infrastructure. It comes as no surprise that airports around the world are, too, beginning to incorporate the ELV systems into their construction. Hamad International Airport is no exception, having been supplied by the Bayanat Engineering group with Extra-low voltage and current systems.

“So, where exactly are these systems used?” one might ask. Spoiler: the employment of the ELV stretches across a number of sectors in the airport framework. It covers anything from security and communications to air conditioning to cell phone and wireless distribution – and these are only a few examples! But before exploring some of uses, let us first explain what Extra-low voltage and current systems are.

Explaining ELV and low current systems
Extra-low voltage and current systems are put in places where a risk of an electricity-related hazard may occur. This, of course, implies a plethora of different infrastructure within an airport. In engineering, a device using the ELV system is one that operates in the range of 50 Volts alternative current (V a.c.) and 120 Volts direct current (V d.c.). Special isolating transformers deliver power to these devices through their secondary windings (coils that carry energy at the transformed voltage to the appliance).

The secondary, as well as the primary windings’ insulation is known for its high impulse withstand levels. In fact, the distance between the live elements (carrying the electrical current to the appliances) in an extra-low voltage system has to at least correspond to that of the two windings.

The various uses of ELV in an airport

Now that the technical side of things is laid out, let us dive into the application of these structures. As previously stated, they are used in a variety of sectors around the aerodrome. Here are a few notable areas of their implementation:

Safety and security 

Let us start with the most important — the safety of anyone present on the airport grounds. In previous articles, we have discussed the many security systems that are put in place in airports around the world.

Extra-low voltage and current systems are also used in devices, tailored to ensure protection of the airport visitors. Namely, they are installed in the fire alarm and fire suppression infrastructure. These are programmed to immediately alert the airport staff about any emergency development within and without the building, while, at the same time, ensuring the overall safety of the aerodrome.

It is important to know that the airport data centres, that store customer information, and therefore have to be efficiently and carefully operated and protected at all times, also rely on the ELV set-up.

Communications and information 

The information-communications sector is highly reliant on the system, too. For instance, ELV is used in command-and-control rooms, wayfinding, as well as in public announcements and messages that one could constantly hear at an airport, as a part of the Public address and voice alarm system (PA/VA). You might have guessed that it is also used in the digital signage and video walls, such as the electronic signboards that display arrival and departure times, or the baggage claim information. Video boards could also be used for a better visibility of information (due to their size), as well as for airport advertising. You might have seen one projecting right in front of the famous Lamp Bear, a landmark of the Hamad International Airport.

Another communications sector where the ELV is used is the satellite and master antenna TV systems, such as that in Hamad International Airport.

Timing and smooth operating of the airport systems

ELV is also used in devices and infrastructure that are responsible for maintaining efficient functioning of the various airport sectors and systems; such devices include master clocks. These could be describes as “directing” parts of the synchronised airport clock network, relaying timing signals to the “slave” clocks. Building management systems (BMS) also operate on ELV.

As we have seen, airports become increasingly reliant on extra-low voltage and current systems, as more and more devices are developed to operate on these structures.

Bayanat Engineering Qatar for exciting meteorological & environmental solutions

The Peninsula

Doha: Meteorology is the science dealing with the atmosphere and its phenomena, including both weather and climate. Where did the practice of meteorology come from?

Though it’s hard to pinpoint exactly where the origins of meteorology lie in history, many attributes its beginnings to Aristotle, who wrote about metrology way back in 350BC.

Bayanat Engineering Qatar is reliable meteorology solutions provider in Qatar with spanning a range of systems and tools.  Meteorology is a key component within many sectors.

The main sectors that incorporate meteorology into their daily workings include aviation, marine, oil and gas, and military. Countries use meteorology in order to predict the climate change and other phenomena like earthquakes, flooding and other – this can help prepare and prevent the consequence and minimize risk for its citizens.

Bayanat Engineering is proud to have built some of the world’s leading weather forecasting systems for Qatar’s meteorology department and other government entities in Qatar.

There is various interesting technology in meteorology, here are some of them:

Cloud seeding: If you want to make it rain – cloud seeding is an answer. Cloud seeding involves modifying a cloud’s structure to increase the chance of precipitation. Cloud seeding is one of the most advanced and helpful tools in meteorology.

Rain gauges: A rain gauge is a solution used by meteorologists and hydrologists to gather and measure the amount of liquid precipitation over an area in a predefined area, period of time. It is used for determining the depth of precipitation (usually in mm ) that occurs over a unit area and thus measuring rainfall amount.

Automated Weather Observing System (AWOS): An AWOS is a configurable weather system, designed specifically for airports.

It delivers real-time information about weather conditions continuously, to ensure pilots can take off in safe weather conditions. AWOS units most commonly report the latest weather updates in 20-minute intervals. This is ideal for airports that need regular and reliable weather reports to ensure optimal flying conditions for every flight.

Meteorological sensors: Meteorological sensors are most typically deployed on buoys, though they are also commonly set up on towers and across runways. Like AWOSs, meteorological sensors accurately measure a variety of weather conditions and other aviation affecting factors.

An essential element of meteorology is understanding how climate conditions can change quickly. Meteorological sensors are usually placed near a body of water and help to measure changes in weather and climate.

There are other solutions and technologies in meteorology that are used in various sectors: MET Forecasting/Visualisation Systems, Runway Visual Range (RVR), Weather RADARs, LIDARs (Windshear/Wake Vortex Measurement), Thermo Dynamic Profiler/RadioMeters, Lightning detection systems, Radiosonde/weather telemetry systems and Weather Decision Support System.

Hassan Ezzeddine, General Manager Bayanat Engineering Qatar (pictured), said: “Every day, our team at Bayanat Engineering Qatar is dedicated to help our customers to undertake meteorological challenges with simplicity. Our priority is to apprehend operational and efficient tools for them. To achieve this goal, we have dedicated staff with experience and set of skills to serve our customers’ needs.”

“Being major player in Qatar market, we have strong partnership with internationally accredited organizations that have valued our support in implementing their technologies in the region,” he said.

Bayanat Engineering: Qatar’s leading meteorological and environmental solutions provider

“Meteorology is the study of the processes in the Earth’s atmosphere that cause particular weather conditions, especially in order to predict the weather.” – Collins Dictionary. 

Meteorology is used in weather forecasting and predictions about the climate – it can be dated over 1,000 years ago but substantial meteorology innovations were not made until the 18th century.

Since the 18th century, however, meteorology technology has advanced significantly. While we do not think about it in our daily activities, it is possible you have come across it without realisation. Whether you check the forecast, take a plane or even encounter rain on the day – you are unknowingly using the meteorology solutions.

Meteorology influences multiple industries and daily processes.

Countries need meteorology and its reliable systems to prepare and monitor extreme weather conditions, to ensure its citizens safety on the daily basis, as well as meteorology technology is crucial in agriculture, military, aviation, environmental, urban planning and other sectors.

Example of meteorology importance is the airport, the more reliable their services will be as they won’t have to cancel flights last-minute, as they will be able to predict and identify weather patterns, Although the climate in Qatar is predominately pleasant and dry, understanding meteorology is still essential for airports in Qatar to ensure they can provide safe and reliable flights for their passengers.

Bayanat Engineering is honoured to have built some of the world’s leading weather forecasting systems for airports, and are happy to play a part in creating systems that keep Oil and Gas industry experts, aviation, military, and other government and civil entities safe and advanced in weather and meteorological solutions in Qatar.

Solutions in various fields

Aviation: It is apparent that weather conditions affect the flight schedule and are important for Air Traffic control and crucial part of aviation industry. Example would be the use of runway visual range (RVR) systems to ensure a clear and safe landing strip for the pilot to land their aircraft. The RVR is calculated using transmissometers, which are a piece of equipment installed along runways to determine the visual range left until the aircraft’s landing point.

Oil and Gas: This industry is another example of the importance of weather solutions as they are located any where from the middle of the ocean to deep underground. Rapid changes in weather conditions or harsh weather phenomena can affect the mining of oil and gas and threaten employees. That’s where meteorology comes in – using equipment such as automated weather observing systems (AWOS) and weather decision support systems (WDSS), oil and gas companies can continuously monitor the weather and modify their working strategies consequently.

Military: The military is responsible for defence involved in the navy and marine, as well as military aviation, all of which depend on weathercasting aspects. This means it is important to monitor it at all times. In addition to that, remote weather monitoring stations are implemented throughout camps in order to achieve the highest and most accurate levels for weather data collection.

Solutions examples

Rain gaugessmart water monitoring. The amount of rainfall is key to industries such as agriculture, which relies on the climate to grow produce. In addition to that, it affects the infrastructure and urban planning development, affects aviation sectors, oil and gas industries and other.

Lightning detection systems: contains a network of sensors which calculate the electromagnetic radiation that is released by lightning. The sensor network uses the radiation data to predict where lightning may strike and at what strength.

Wind profiler: This is a piece of equipment that is used to monitor wind speed, direction and conditions. Wind profilers use sound waves (SODAR) or radar waves (RADAR) to detect these conditions at various levels above the ground – from sea level right up to the troposhere (zero to 17 kilometres above sea level).
These wind measurement systems are able to detect vertical and horizontal wind speed, thermal stratification, turbulence and direction, as well as measuring remote temperature profiles within the atmosphere.

Outdoor air purifiers: with environmental issues being of growing worldwide worry, companies and governments around the world are looking at ways to reduce carbon emissions and reverse the negative impacts of pollution on our planet. Air pollution from vehicle emissions, agricultural activities and other industries are likely to blame for the increase in human respiratory illnesses – not to mention the devastating effects of rising global temperatures. Pollution is a significant problem in many countries – particularly in urban environments. Industries such as transportation and aviation have a large role to play in helping to keep our air clean, so companies are increasingly looking for ways to cancel out emissions.

Qatar rain gauges and their importance

Why are rain gauges important?
Monitoring rainfall has never been more important as part of commitments to improve water cycle management in ever-challenging climates.
An increasingly large global population is facing a growing number of climate challenges, including heat waves, droughts, floods and natural disasters, making water cycle management and smart monitoring of meteorological conditions extremely important.
Smart water management, including the use of rain gauges for monitoring, can have a range of benefits. These include the prevention of wastage and the provision of better outcomes based on information about the lifecycle of water.
Monitoring rainwater, for example, can provide vital information about the nature of this water and pressure levels. It can also offer data on purification and temperature, and even deliver information on conditions in more remote locations.
The benefits of this for aviation:  Weather monitoring is vital for the aviation sector, especially given the dangers posed to pilots from adverse weather conditions. Important monitoring for the aviation industry can include everything from RADARs used by air traffic control to monitor cloud systems to decision support systems to offer short-term forecasts to help pilots prepare for conditions.
Bayanat Engineering Qatar is a key player when it comes to providing this information and has built airport weather forecasting systems used at airports around the world. This equipment is vital when it comes to keeping pilots safe and ensuring a smooth and pleasurable experience for passengers. Rainfall management can play a key part in this and in overall water management, delivering a multitude of specialist information to help protect both human life and the wider planet.
Rainfall has also long been known to have an impact on aviation safety. It can have an adverse effect on aerodynamics, as well as causing difficulties due to visibility impairment, for example.
Bayanat Engineering was chosen to provide and install 50 rain gauges by the Qatar Civil Aviation Authority (Qatar Meteorology Department) to help it to ensure that it is up-to-date with meteorological standards and to help it to develop working mechanisms. Automatic weather monitoring stations, or AWOS (Automated Weather Observing Systems), provide continuous meteorological information in real-time. They are commonly used and controlled by providers in the aviation sector. They have functions in terms of climatology and meteorology and offer information that is vital for maintaining safety standards. The measurements taken by these systems depend on specific configuration, but typically include the likes of barometric pressure, wind gusts and wind speed, dew point and temperature, sky conditions, precipitation, freezing rain, thunderstorms and surface conditions on runways.
The role of Bayanat Engineering in Qatar rain gauge supply: Bayanat Engineering Qatar was awarded the project to supply and test the Automatic Rain Gauge initiative. This contract features the supply of 50 units including Dataloggers, rain gauges and 4G modems to monitor rainfall and how intense this is.
Rain gauge system – how does it work?
A rain gauge is a system used by meteorologists to measure the amount of rainfall over a particular area. It is also used in aviation to inform flight-related decisions. There are several types of rain gauges, and most collect precipitation to give a reading – usually in millimetres of height across each square metre. Rainfall is measured over a certain period – usually a day. However, in aviation, readings are often taken at much shorter intervals.
Let’s take a closer look at the types of rain gauges and their uses.
Manual versus automatic rain gauge systems: Rain gauge systems can measure rainfall either automatically or manually. Manual systems tend to be simpler, whereas companies will use automatic systems in instances where more precision is required, such as for aviation purposes.
Manual rain gauges have their limitations in their accuracy. This is because some rainfall will often stick to the gauge’s sides in the form of droplets, thus causing the accurate rain levels to be under-recorded by small amounts.
Rain gauges may also be challenging to use in extreme weather conditions. String storms and cyclones, for example, may cause wind damage to the device. Wind can also cause inaccuracies in readings as it may blow the water out of the gauge after it has landed. Another factor that can impact the accuracy of rain gauges is cold weather. The formation of ice in the gauge can block the entrance, leaving new water unable to enter. Many of the more advanced rain measurement systems are equipped with built-in heating systems to prevent ice build-up.
To summarise, a rain gauge is a standard device to measure rainfall and is an essential tool in informing aviation decisions.

Bayanat Engineering: Specialists in airport lighting, signage projects

Have you ever peered out of your aircraft window and spied multicoloured lights that line the runway as your flight prepares to take off? Their gleam and colour catch the eye, but their purpose is far more important than mere aesthetics. In fact, they constitute specialised lighting for runway and airport and play a crucial role in ensuring the safe passage of planes while on or near the ground.
As for the different colours, they are arranged in precise patterns, that are universally recognised by the different international airports, and represent the various points of the taxiway and runway. This helps orient the pilot and other users of the aeronautical ground when the visibility is low. There are about 9 colour combinations of specialised lighting found in airports.
The different lighting systems of the airport and its proximity
• Taxiways and runways: Taxiway edge lights are blue. They can be both recessed or elevated and are sometimes followed by green in-pavement centreline lights. Their colour is different from that of the runways, which are represented by a white centreline that gradually turns amber towards the approaching of the lift-off.
• Approach and apron lighting: Approaching the runway, a pilot needs to be guided towards its exact whereabouts. There are special series of lightbars and strobe lights lining this passageway, called the approach lighting system (ALS).  At the heart of the airport, aprons, or areas where passengers climb onboard and leave, where aircrafts are parked upon arrival, are marked by apron floodlights. Not only do they help maintain overall security in this zone, but also provide appropriate illumination for the embarkation and debarkation of passengers and cargo.
• Heliport lighting: Outside the usual taxiways and runways, one can find heliports, or areas delimited for the take-off and landing of helicopters. These have a special lighting system as well. You might have noticed in movies that their lights are arranged in a circular or square pattern. Sometimes, the airplane taxiway is in the heliport’s proximity. Therefore, to avoid confusing the two, the latter is lined with yellow lights.
• The significance of signage: Signage is another obligatory means of guiding pilots and vehicles that operate around the taxiways and runways, as it indicates direction and provides information. Two main types can be distinguished: Operational guidance signs and mandatory instruction signs. Marked by special letters, numbers, symbols and, of course, colour, they are just as crucial in ensuring safe passage of planes, although, airports smaller than Hamad International Airport may have little to no such signs.
Together, these luminaries and their ancillaries make up the airfield ground lighting. All the different illumination types could be controlled simultaneously or airfield by airfield via the lighting control and monitoring systems of the airport (ALCMS). The intensity of the lights could also be alternated between high, medium and low for appropriate meteorological conditions. It is important to measure their precise intensity. Photometry and calibration (MALMS) are, hence, used to help with maintenance and measuring of the ground light of the airfield. The measurements of beam intensity and orientation of the Airfield Lighting should be done regularly. Airports also have to submit a report about their installations, which complies with the International Civil Aviation Organisation (ICAO) standards and meets the safety regulation requirements for a Preventive Maintenance System for Airfield Lighting.
Outside the airport
Obstruction lights: Specialised lighting is employed outside the aerodromes just as well. On your night flights, it probably occurred to you to find piercing red lights on the rooftops of the Doha skyline, or other towers and tall buildings, as you fly above. It is absolutely necessary to mark elevated structures with these lights to avoid any accidents and indicate their exact position for the passing aircrafts in gloomy or dark conditions. The rules of the Federal Aviation Administration (FAA) prescribe that the buildings outreaching 200 feet (60 m) above ground be marked by paint or luminaries. As per ICAO, this height is lowered down to about 148 feet (45 m).
These beacon and obstruction lightings vary according to terrain, geographic location, weather conditions of the area, but also types of structures. Interestingly, wind turbines have their own prescribed norms for lighting. So, what are the different types of obstruction lights?  There are the LED elevated aviation red obstruction lights. Their light is omnidirectional and has an Infra-red option. The other two types are Medium-intensity and high-intensity obstruction white lights.
Bayanat Engineering, an expert in the area, has been a provider of high-quality specialised lighting for airfields and heliports, guidance signage, obstruction and beacon lighting, MALMS and ALCMS in various large international airports. In effect, Bayanat Engineering has led specialised lighting and signage projects in Doha’s very own Hamad International Airport.

Bayanat Engineering Qatar: Leader in meteorology systems

 

Meteorology is a part of everyday life. The aviation, marine, oil and gas, and military sectors use meteorological tools in different ways. Bayanat Engineering Qatar is the leader in the market.
Aviation: The aviation industry employs the use of runway visual range (RVR) systems to ensure a clear and safe landing strip for the pilot to land their aircraft. The RVR is calculated using transmissometers, a piece of equipment installed along runways to determine the visual range left until the aircraft’s landing point.
Oil and gas: The oil and gas procurement industry is unpredictable. Working anywhere from the middle of the ocean to deep under the ground, sudden changes in weather conditions can impact the harvesting of oil and gas and endanger workers. This is where meteorology comes in. Using equipment such as Automated Weather Observing Systems (AWOS) and Weather Decision Support Systems (WDSS), oil and gas firms can constantly monitor the weather and change their working strategies accordingly.
Military: Meteorology is used there too. Navy and Marine, as well as the Military Aviation depend on the meteorology aspects.
AWOS: One of the oldest types of automated weather monitoring units, AWOS units report the latest weather updates in 20-minute intervals. This is ideal for airports that need regular and reliable weather reports to ensure optimal flying conditions for every flight. AWOS systems are fully configurable to specific needs and can include any number of the following measurements — Barometric pressure, Wind speed, gust, and direction; Visibility, Identification of precipitation (e.g drizzle, snow, rain), and Sky condition, including cloud ceiling height.
Meteorological sensors: These are typically deployed on buoys, though they are also set up on towers and across runways. Like AWOS, these sensors accurately measure a variety of weather conditions and other aviation affecting factors. At Bayanat, we install meteorological sensors that measure  Wind, Barometric pressure, Temperature, Humidity, Cloud ceiling height, Precipitation, and Solar radiation.
Runway Visual Range: Another piece of crucial airport equipment that Bayanat offers installation of, is transmissometers. They are installed at the side of the runway to allow for the measurement of the RVR. Transmissometers are a modern method of RVR calculation. Transmissometers  allow for more precise and reliable measurements not dependent on the eyesight quality of a worker. This guarantees a safer and more guided landing for pilots.
MET Forecasting/Visualization Systems: MET forecasting is another essential cog that keeps airport business moving smoothly. By forecasting the weather through visualization systems such as the ones offered by Bayanat, airports can ensure that they can anticipate any weather issues with maximum efficiency and warning time. These are the same MET forecasting systems used by weather reporters.
Weather Radars: Also known as a Doppler weather radar or weather surveillance radar (WSR), weather radars are used specifically to track precipitation, including its type (snow, rain, etc), motion, and intensity. Modern weather radars are incredibly useful as they not only measure current rain but can also award experts foresight, giving the ability to preempt intense and potentially disruptive precipitation.
LiDAR (Wind shear/Wake Vortex Measurement): Standing for Light Detection and Ranging, LiDAR allows for the measurement of distances across the earth, most specifically its surface characteristics including wind shear. Wind shear can significantly affect the flight quality and path of aircraft, so trusting Bayanat to install LiDAR monitoring equipment could be invaluable.
Lightning detection systems: Bayanat’s lightning detection systems are one of the most advanced and reliable units in the market. Measuring down to the exact discharge location and the polarity, strength, and lightning parameters, airports will receive highly detailed and precise data during every storm.
Radiometers: Used for the thermodynamic profiling of energy, radiometers are devices that measure and monitor the flux of electromagnetic radiation. Radiometers quantify invisible types of light, including infrared and UV, helping to widen the range of data on the light spectrum.
Radiosonde: Usually carried into the atmosphere via weather balloon, radiosondes are remote weather telemetry systems that measure a range of weather parameters and transmit the data to a control base back on earth. This is ideal for airports as they can glean an accurate report of the environment up in the air, including checking for ideal flight conditions and preempting any problematic conditions.
Weather Decision Support Systems: For holistic weather decision support, any airport should invest in WDSS offered by Bayanat. WDSSs take all data attained by the above equipment and utilise it to predict and detect any change in the weather, including rare phenomena.
