Sustainable solutions for airports in 2021

Sustainable solutions for airports in 2021

 

As airports return to normal and passengers around the world take to the skies again, there is growing pressure for Aeronautics and Aerospace companies to switch to a more sustainable model. With global emissions rising and air travel accountable for 2% of global CO2 emissions, more and more people are looking for sustainable solutions when it comes to air travel. From rainwater harvesting stations to using recycled materials in airport expansions, some of the worlds’ best airports are responding to this new challenge with innovation and creativity.

 

Switching to sustainable power

 

Perhaps the biggest concern for the aviation industry is the fuel they use, from the power supply for Information Display Systems to the fuel used by aircraft. Innovations in aviation technology have led to a wealth of more sustainable and less harmful fuel solutions, with a push towards renewable energy in airports. More and more airports are using biofuels and alternative energy sources to power their operations, like Denver International airport which has the largest solar power farm at a commercial airport in the US with four on-airport solar arrays and the Galapagos Ecological Airport which was designed in 2012 to run completely on solar and wind power.

 

Reducing waste in airports

 

Improving efficiency by reducing waste is both good for the balance sheet and for the planet. From the materials used in the construction of airport expansions to wasted water, more and more airports are looking for ways to reduce their waste. Advanced environmental management systems can also be a game-changer, with an in-depth and thorough approach to reducing waste across the entire airport. Initiatives to encourage passengers to divert waste from landfills can also be effective, such as water bottle refilling stations to reduce plastic consumption and recycling facilities throughout the airport. Technologies such as low-flow bathroom fixtures to save water can make a big impact, considering the huge scale of international airports and the number of people who use them. More and more airports are using recycled and reclaimed materials in their construction and expansions, which reduces emissions and diverts materials from landfills.

 

Innovative new technology

 

There has been a wave of new, innovative technologies designed to help the aviation industry reduce its carbon impact. Using technologies such as environmentally friendly asphalt for airport runways can make a big difference, with far lower heating temperatures required and far less energy needed. Rainwater harvesting stations are another innovative system that is being utilised in airports across the world. Biofuel-powered heating systems are another innovative and effective new technology, like the one used in Stockholm Arlanda Airport in Sweden which achieved carbon neutrality in 2009. Switching to more energy-efficient fixtures and fittings can be another powerful way to reduce waste, such as choosing low-power LED lighting or installing underground energy piles to heat and cool terminals, like Zurich Airport which has reduced its carbon emissions by 30% since 1991.

 

 

Why is marine and navy vessel tracking important?

Naval and marine vessels are used for a wide variety of purposes across the globe, including trade, fishing, research, and military use. These vessels can be tracked using different vessel tracking systems, depending on the needs of the individual.

 

Accurate vessel tracking systems are an important feature across all marine and naval industries, both to ensure the safety of the vessel and all of its crew, as well as providing essential data that can be used to streamline and improve vessel management and scheduling.

 

What kinds of vessel tracking systems are commonly used today?

 

Vessels have various options when it comes to vessel tracking, from satellite-based GPS technology that can monitor vessels in real-time to AIS transmitter data which is monitored by ground stations or read remotely via satellite.

 

Most contemporary tracking systems utilize GPS, or Global Positioning System, technology. GPS technology was originally developed by the United States Department of Defense but is now widespread across the world, with smartphones and cars using it to navigate cities and the routes between them.

 

Naval vessels are no different, also using satellite-driven GPS technology to accurately pinpoint a vessel’s location in the water, as well as offering information to aid navigation and wayfinding.

 

AIS, or Automatic Identification System, is a common form of vessel tracking technology that utilizes GPS. AIS technology transmits information about a vessel’s identity, speed, and location to other vessels in the vicinity. The United States Coast Guard operates AIS technology across their nation’s waterways as a safety measure for ships at sea. AIS transmitters can be read by ground stations or monitored remotely by satellite for security purposes when necessary.

 

Ship Loc is another form of vessel tracking system that utilizes GPS with extra functions, such as warning people on the land about marine traffic near them so they are aware of the risk posed by passing vessels. Ship Loc can also give readings of data pertaining to a ship’s location including air pressure in the oceanic area, wave pressure, and other relevant details.

 

Why is accurate vessel tracking important?

 

Many naval and marine vessels rely on vessel tracking systems for safety and navigation. Accurate vessel tracking not only means that a vessel and its crew can be quickly located and rescued should something go wrong, but it also makes it easier to navigate safe passage, especially in adverse weather conditions.

 

Challenges to vessel tracking include limitations on distance and satellite transmission problems, both of which can hinder the reliability and accuracy of vessel tracking in situations where it is most needed. The key to improving connectivity and encouraging the adoption of vessel tracking technology across all marine and navy sectors is in overcoming these limitations: a challenge that contemporary tracking technology is no doubt ready for.

What is cloud seeding and why is it important in the aviation industry?

Weather is an important element to consider when planning the routes and schedules for air traffic. This is because different types of weather can impact air traffic in a number of ways, including the speed of flight and visibility. Precipitation and fog are two of the most common weather concerns within the aviation industry due to the ways in which they disrupt normal flight proceedings.

 

This is where the process of cloud seeding comes in. But what exactly is cloud seeding and why is it so important within the aviation industry? Read on to find out more.

 

What is cloud seeding?

 

Cloud seeding is the incredibly technical process of modifying the microphysical characteristics of clouds in order to change either the type of precipitation or the amount of precipitation. Cloud seeding is done by artificially dispersing a substance into the cloud, such as condensation nuclei. This addition of condensation nuclei forms the basis upon which additional raindrops or snowflakes can form, leading to a change in the weather.

 

What are the benefits of cloud seeding?

 

When it comes to aeronautics, cloud seeding is a useful and essential process. There are many benefits of cloud seeding, including the following:

 

  • Cloud seeding can reduce the amount of fog by turning the fog into rain, therefore improving the visibility of those piloting aircraft.

 

  • Cloud seeding can improve the safety of airborne crafts by decreasing the number of hailstone particles present in the air, again by changing the particles into raindrops.

 

  • Cloud seeding allows for the more predictable regulation of the weather, leading to more consistent and reliable flight plans for current and future aircrafts.

 

How is cloud seeding carried out?

 

As mentioned previously, cloud seeding is the process of modifying the structure of a cloud by adding particles to alter the chemical balance of the cloud in order to increase or decrease precipitation.

 

The process of physically adding these particles to the clouds is typically achieved in one of the two following ways:

 

1. By using large cannons to shoot the particles into the sky

 

This first method of cloud seeding is a ground-based technique that utilises cannons in order to shoot the particles into the sky. Cannon-based cloud seeding is particularly effective at altering lower altitude clouds, but it is still effective at modifying those higher up too.

 

2. By using airplanes to drop the particles into the clouds from above

 

The second method of cloud seeding is an airborne technique that involves airplanes dropping the affecting particles into clouds from above. Airborne cloud seeding can alter clouds at any altitude, depending on the height of the aircraft.

 

 

Overall, cloud seeding is an efficient form of weather management that allows aeronautical experts to alter the weather conditions in order to benefit air traffic. The reasons for cloud seeding are plenty and include improving visibility and navigational abilities of pilots, decreasing the risk of hailstone damage and regulating weather conditions in order to plan flight routes more adeptly.

Looking forward: Aerospace industry trends

The aerospace industry is always evolving and adapting to consumer habits and driving innovation through new developments. Major aircraft manufacturers are already looking ahead to plan for the next shift in the industry, from pushing the boundaries of technology to overhauling entire fleets of aircraft.

 

All of this innovation within the industry has encouraged a lot of growth and expansion, which is only good news for aviation and the aerospace sector. To determine how this industry is going to look moving forward, it’s important to identify trends within aerospace. This article is going to look at some key trends to watch in the aerospace industry, from tech innovations to overhauling older aircraft fleets.

 

The push for technological innovation

 

Efficiency is a major talking point in the aerospace industry looking forward, with streamlined interior cabin developments and advanced avionics being used to make for more efficient flights. Other innovations, such as noise-reduction of aircraft, appear to be on the horizon for much of the industry. All of these integrations will make for a safer, more comfortable experience in the skies for passengers.

 

New-age materials such as composites and advanced manufacturing developments will also be shaping trends in the near future for aerospace. This, along with the implementation of new electrical systems, could re-shape how aircraft are designed and manufactured, which could alter the current supply chain dramatically.

 

Improvements in repairs and fleet overhauls

 

Looking towards the next generation of aircraft, it is apparent that improvements have been made across the board, from materials and components to the systems and electronics used. These changes will no doubt create new opportunities for the industry, but there will also be challenges for the maintenance, repair and overhaul sector to contend with. Switching from mainly aluminium frames to composite materials is a legitimate concern that has yet to be addressed.

 

Although composite material has been used in the past, the scale of its use is going to increase dramatically. By their design, metallic aircraft crumple and bend if there is ever a collision, but composite materials don’t. Although this might seem like a positive, it is actually more difficult to assess the damage on a composite aircraft than a metallic one. The visual inspection of dents is possible with aluminium because it bends, but you need to use ultrasonic scanning to detect damage in composite materials. What this means is that the repair sector will need to adapt and invest in new equipment and training.

 

Embracing digital

 

The maintenance sector is set to undergo a number of changes as a result of the push for digitisation. As the technology found on aircraft becomes more complex, technicians and maintenance workers will need to become more adept at troubleshooting and diagnostics work.

 

Thankfully, digitisation can also lend this sector a helping hand in a number of innovative ways. Embracing virtual reality training can help technicians step into a digital aircraft and learn how to repair and replace components virtually. Other inherent benefits of switching to digital include ditching paper instruction booklets for cloud-based ones. This makes it easier to access information while working and cuts back on paper consumption.

A Guide to Essential Airport Terminology and its Origins

Air travel has been around for decades, and over time the aviation industry has built up a wealth of airport terms that are used to make communication between airport staff quick and simple. From the term ‘airport’ itself to more technical acronyms, there is a wealth of unique terminology used in every airport.

 

It’s important for both passengers and aviation employees to understand these terms. Let’s first take a look at the word ‘airport’ itself, and where this word comes from, before going over some of the most essential airport terminologies that are used in airports around the world today.

 

What is the origin of the word ‘airport’?

 

The word ‘airport’ comes from the words ‘aerodrome’ and ‘port’. An aerodrome is any location from which aircraft take flight, which means that all airports are aerodromes, but not all aerodromes are airports. To achieve ‘airport’ status, in some regions it’s necessary to have been certified as an airport by the local jurisdiction. More generally, an airport is bigger, with more terminals, than a simple aerodrome. The ‘port’ part of the word no doubt originates from maritime ports, which describe any location where ships and boats arrive and leave from.

 

College Park Airport, in Maryland, US, is generally accepted to be the world’s oldest airport, operating since 1909, while Hamburg Airport, opened in 1911, is the world’s oldest commercial airport still in operation. Since the 1960s, the number of airports around the world has multiplied quickly, with air travel becoming more and more accessible with each passing decade to the average customer.

 

Essential Airport Terminology

 

ASMGCS: ASMGCS, or Advanced Surface Movement Guidance & Control Systems, are high-tech navigation and tracking systems that help air traffic controllers guide planes to the appropriate runway.

 

ATC: ATC, or Air Traffic Control, refers to the team of controllers who keep an eye on an airplane’s flight path and command every aspect of a flight.

 

Customs: This is the building where passengers and visitors must go through the process of entering a country. The customs officer checks passports, visas, travel documents, customs declarations, and health certificates before allowing you to enter the country.

 

Ground stop: When a ‘ground stop’ is enforced, this means that no aircraft is permitted to take off or land at the airport. This could be due to bad weather such as storms, or even terrorist threats.

 

Slot: This is the scheduled time for take-off and arrival for a particular flight.

 

Taxiway: This is a specialized path for aircraft taxiing that runs parallel to one or more runways. Taxi routes are usually marked with lights (red and green) on both sides of the runway so that pilots can recognize them as they approach their turn-off point from either direction.

 

Terminal: This is the building from which passengers either enter or leave an airport. A terminal contains gates for the aircraft as well as luggage carousels and other facilities. The word ‘terminal’ is used because this is where a passenger’s flight journey terminates.

 

UHF and VHF: Ultra-high frequencies (UHF) and Very-high frequencies (VHF) are used for radio communications across airports, between ATC teams, and flight teams.

Prioritising the Passenger Journey at the HIA

The Hamad International Airport, or HIA, is the only international airport in Qatar. Passenger numbers fell during the pandemic, but the airport has recently seen a marked increase in traffic as Covid-19 restrictions are lifted across the world. This has resulted in a 381% increase in passenger traffic between April 2020 and April 2021.

 

As the airport returns to pre-pandemic traffic levels, HIA management teams will be starting to think about how to streamline the passenger journey in one of the world’s busiest airports.

 

What is the Passenger Journey?

The passenger journey is the journey each passenger takes throughout each area of an airport, from arriving at the airport to checking in and boarding the plane. Streamlining the passenger journey is key to improving customer satisfaction, as well as managing airport traffic by reducing the amount of time each passenger has to spend at each stage of the journey.

 

Broadly speaking, a passenger journey includes:

– Arriving at the airport, including any identity and security checks made here.

– Placing flight bookings and shopping at the airport.

– Checking in to a flight.

– Locating the flight terminal and boarding the plane.

– Collecting and dropping off baggage.

– Getting through security and border control.

 

The passenger journey can take an hour or more, making it a substantial consideration both for passengers themselves and airport managers.

 

How can the HIA use technology to put the passenger journey at the forefront of airport management?

 

Streamlining the passenger journey has been made possible by modern technology. Contactless technology is playing a huge role in improving the passenger journey; it can be used to help when dealing with safety checks and queues, allowing large volumes of passengers to check-in quickly and quietly. Of course, in a post-Covid world, contactless technology will also play an important role in minimizing virus transmission across the airport.

 

The HIA can also make use of surveillance technology in a similar way, using surveillance to manage baggage volumes and security queues. CCTV and other kinds of surveillance can also be used to feedback data relating to runway and flight status which can then be communicated to passengers using apps and text notifications: if a flight is boarding late, let your passengers know sooner rather than later.

 

From biometric scanners to notifications and apps, much of the technology that is employed in airports around the world is designed to make the passenger journey faster and more efficient. But what about making it more pleasant? Simple investments into air conditioning and dining facilities can also help to improve the passenger journey.

 

How can Bayanat Engineering help to improve the passenger journey at the HIA?

 

At HIA or any airport, it’s clear that technology is key to improving passenger journeys in the 21st century. At Bayanat Engineering, we can install a number of systems designed to improve passenger journeys and streamline workloads for airport staff at the same time, including:

 

– Passenger check-in and boarding solutions (CUTE/CUPPS)

– Baggage Reconciliation Systems (BRS)

– Baggage Handling Systems (BHS)

– Queue Management Systems (QMS)

– Passenger Tracking Systems

 

Using our IT solutions, you can track and record the passenger journey in your airport, identifying areas for improvement and installing cutting-edge technology to streamline the passenger journey from entry to takeoff.

 

The HIA is consistently ranked as one of the world’s top airports, in part because the management team working at the HIA is willing to invest in world-leading technology with a focus on improving passenger satisfaction.

How are airports increasing airside traffic efficiency?

Mid-size and tier-one airports are facing increasingly complicated airside traffic demands, with flight traffic peaking in recent years. These higher airside traffic demands are putting pressure on minute-to-minute operational personnel, airport planning, and ATCOs, so what are airports doing to mitigate this increase in traffic?

 

What is Airside Traffic?

Airside is the part of an airport used by aircraft for takeoffs, landings, loading, and unloading. There are a wide variety of airside vehicles that all have different jobs, from baggage tractors and trailers to refueling trucks and passenger buses.

With so many vehicles operating airside, it’s essential to control traffic to avoid collisions with vehicles, pedestrians, and aircraft.

 

Airside Traffic Automation

Despite the COVID-19 pandemic’s devastating impact on the air travel industry, it has also presented an opportunity for governments and airport operators to meet 21st-century challenges. Artificial intelligence, data analytics, robotics, and machine learning can be used to put environmental responsibility, customer service, and safety at the forefront, so let’s take a look at how automation is being used to streamline airside traffic operations.

 

Robot Ground Handling

Removing personnel from dangerous working environments is one of the main advantages of automation, as repetitive, low-value tasks can be replaced with digital solutions.

With passenger volumes expected to increase following the COVID-19 pandemic, increasing efficiency via ground handling automation is being considered by airports around the world. Using artificial intelligence has been designed to deliver and manage baggage in bulk to different areas of an airport, reducing operational costs by up to 50%.

 

Automated Security Screening

One of the key factors of having efficient airside operations is having a swift and straightforward baggage handling process. Transporting customer baggage from check-in points to aircraft and back again is becoming increasingly automated in airports across the globe, improving baggage screening processes and operational efficiency.

For example, Detroit Metropolitan Airport has implemented an autonomous cart system to relieve transportation security staff from the tasks of moving checked bags on and off aircraft. Using set routes labeled by magnetic tape, these carts are designed to deliver flagged bags from an assigned conveyer belt to an inspection station before transferring them to another conveyor belt once they have passed a screening.

 

Bird Control Drones

While drones have been perceived to pose a security threat for some airports, others, such as Edmonton International Airport (EIA), have adopted them to carry out bird control tasks to lure flocks away and prevent them from accessing the airport space.

A bird strike (a collision between a bird and an engine) is particularly dangerous for smaller aircraft vehicles, as it can cause significant damage to jet-engine aircraft and can result in a loss of thrust. To mitigate this problem, Edmonton International Airport is now on track to implement the world’s first regular airport drone delivery service.

From ground handling to baggage screening and foreign object control, automation is making waves in airside traffic operations to help the air travel industry rebuild after the catastrophic effects of COVID-19.

Weather Solutions and Meteorology from Bayanat Engineering Qatar

When you think about weather monitoring, in all likelihood the first thing you think of is national weather forecasts on the news, giving you an extremely wide idea of what the weather is going to be like. In the case of airports, you need to have access to the most up-to-date information, offering pinpoint precision to inform your planes and keep passengers safe. Here are just a few of the weather monitoring systems an airport needs, and what they do.

 

Wind Profilers

The most dangerous parts of a flight are the take-off and the landing, this is because planes are vulnerable to wind. At lower speeds and closer to a collision, a strong gust could knock a plane off course and potentially lead to an incident.

Wind profilers are weather detection equipment that makes use of SODAR and RADAR to detect wind speed and direction at different heights. These readings can be taken from a range of altitudes, up to 17km above sea level. This makes it far simpler to guide a plane to a safe landing, as pilots don’t need to worry about the impact of wind on their approach. These systems also have a tangible environmental benefit, as wind profilers mean we are able to help to plot optimal courses, rather than seeing pilots need to take several attempts at landing due to poor conditions.

 

Weather RADARs

Of course, another key feature of weather detection in an airport setting is weather RADAR. This is a key part of the weather detection process that the Bayanat Engineering team has worked with extensively, from design to supply, installation, and configuration of weather radar rainbow user workstations. Weather RADARs have worked in the same way since their invention in the Second World War. Radio waves are beamed out directionally, and objects in the air like rain and snow will cause these beams to scatter and return, showing up on sensors.

Ensuring effective weather RADAR is key for any modern airport, but especially for ones by the sea such as Hamad International Airport (HIA). Qatar is facing a major international event in the form of the 2022 FIFA World Cup, and the bulk of viewers are coming in from overseas. By helping to guide pilots around storms and major meteorological events, Bayanat Engineering and Hamad International Airport are doing everything we can to ensure that the event is as smooth as can be.

 

Runway Visual Range (RVR)

Runway Visual Range is the distance you can expect to see horizontally down a runway, helped by technology such as High-Intensity Runway Lights (HIRL) and a selection of beacon lighting features. This is always likely to fall in the event of adverse weather, however, being able to keep Runway Visual Range as high as can be is key to a safe landing. After all, the last thing a major company such as QP Oil and Gas need is dangerous or anxiety-inducing landings when flying delegates in to complete key deals.

By making use of weather RADAR you can keep RVR as high as possible, ensuring that landings are attempted in only safe situations where the pilot can see a significant proportion of the runway.

 

The Key to Safety

These are just a few of Bayanat Engineering’s dozens of weather solutions that support airports in making flights as safe as can be. By developing the most advanced technology possible Bayanat Engineering are able to protect pilots and passengers from emergencies, making sure that everyone feels safe and secure on their trips around the world.

What is vital for safety at the airport?

Airports are notoriously busy spaces, with billions of people from all over the world traveling through these hubs each year. The frenetic, busy nature of airports raises a lot of challenges in terms of traveler safety and security. So, what is vital for safety at the airport?

We’re going to take a look at some of the precautionary measures that airports put in place to ensure utmost safety and security on-site.

 

Radars

Radars have been used since World War 2 as a means to identify aircraft and provide a full picture of the surrounding skies. A surveillance radar is a vital aspect of airport safety as it allows air traffic controllers to accurately detect the location of planes in the sky. This can help with providing directions to pilots, as well as assessing potential threats and unauthorised flights.

As air traffic began to expand over the years, there was a need to expand the radar system further. Secondary surveillance radar is also a common feature in air traffic control, as it allows for a much more precise reading. Generally, this type of system works best within a 60-mile radius of the radar site and can provide rapid identification of aircraft in distress.

 

Drone Detection

Drones have grown to become a genuine threat to airport safety, as the general public can cause major disruptions for the flight path of aeroplanes. There is a legitimate risk of mid-air collisions as a result of drones flying through their airspace, but these little drones also pose a threat to communications.

By operating through specific radio frequencies, drones can jam cockpit communications, leaving the pilot powerless to control the plane which could result in a catastrophic crash.

Drone detection systems come in a few different iterations, but ultimately their purpose is the same – to detect errant drones to quickly identify the threat of unwanted drones within the airspace of an airport.

 

The following are three common methods of drone detection at airports:

 

– Radiofrequency (RF) drone detection

– Radar drone detection

– Visual tracking drone detection

 

Security within the airport

One of the most comprehensive ways that airports are kept safe is through their own security procedures. These have advanced a great deal over the years, allowing for a safer environment for travellers and staff.

 

X-ray Machines

X-ray machines have been employed at airports as a way to inspect baggage without having to open them up. This innovative security procedure scans luggage that passes through an x-ray machine, where a member of staff will check the real-time images and inspect for anything nefarious.

 

Full-body Scanning

One of the more recent security developments for airports was the implementation of full-body scanners. These hefty machines have passengers stand in place while their body is scanned through a machine. This is designed to pick up any smuggled contraband including explosives, weaponry and drugs.

 

Staying safe at the airport

There are a lot of measures that you can take to stay safe at the airport, and a lot of them are relatively easy to follow and common sense in most cases. Airports put an incredible amount of effort into ensuring our safety, with innovative technology safeguarding us against some truly horrific threats. So next time you go to an airport, consider all of the vital aspects that go into making it as safe as possible.

What is the state of anti-drone technology in 2021?

Drone technology has advanced significantly over the last few decades. Machines that were once far too expensive for anyone other than a well-funded military are now available to the average consumer. In recent years, the proliferation of consumer drones has presented significant challenges for the aerospace industry, which now has to share air space with small, unmanned vehicles. If drone pilots are flying their drones responsibly, they should always be well away from any commercial aircraft, but a growing number of near-misses has prompted calls from the industry for more stringent measures to ensure the safety of all aircraft.

 

For as long as there have been drones, there has been researched into anti-drone technology. Like the drones themselves, this was initially the purview of the military. But now that drones aren’t restricted to the battlefield, interest in anti-drone technology has skyrocketed. The infamous Gatwick Airport incident highlighted the need for more robust measures than we have at present for many people. Fortunately, there are now some effective solutions available.

 

Drone Monitoring Equipment

 

Monitoring equipment enables the detection, location, and classification of active drones. It can also alert operators to the presence of drones and provide advanced warning of any that are incoming. Not all monitoring equipment offers all of these features.

 

There are two types of drone monitors: active and passive. Passive monitoring continually scans the surrounding area and indicates if any drones are detected. Active monitoring sends out signals and measures what comes back. It is active monitoring equipment that can provide specific details about any drone it detects.

 

Drone monitoring enables the deployment of countermeasures rapidly once a craft is detected. It can also provide information that makes choosing appropriate measures easier.

 

RF Jammers

 

A radio frequency jammer is a unit that emits large amounts of radio waves. The emissions are focused in a single direction to target the drone without interfering with other nearby equipment. The idea is to overwhelm the drone and block the radio signals from the controller. Depending on the drone, this can result in drones making a controlled landing, a crash landing, or flying off aimlessly.

 

RF jammers are short-range and even with directionality, they can impact other equipment.

 

GPS Spoofers

 

GPS spoofing hijacks the drone’s communication with GPS satellites and makes it think it’s somewhere completely different. Altering the GPS coordinates in real-time enables the spoofer to control the drone and redirect it away from sensitive areas, or land it for retrieval.

 

GPS spoofing is another short-range measure and can interfere with other equipment that relies on GPS. The benefit is that the operator gains control of the drone and doesn’t have to worry about an uncontrolled descent.

 

HPM Devices

 

High power microwave devices emit electromagnetic pulses that can interfere with radio signals or damage electronic components, depending on the strength of the device. Like RF jammers, these are designed to direct their energy in one direction to minimize collateral damage.

 

HPM devices are the last resort in most cases. They are expensive and have the potential to cause a lot of collateral damage.

 

Other examples of anti-drone technology can be as advanced as high energy lasers, or as simple as a net launcher. Birds of prey have even been trained to hunt drones and snatch them out of the sky with incredible effectiveness. As drones become more affordable and more common, anti-drone technology is only going to become more important for the aerospace industry.
