ADS-B Aviation Technology: Things to Know

Countries across the globe are trying to implement a more efficient way to track aircraft. Automatic Dependent Surveillance-Broadcast (ADS-B) has emerged as a useful technology to accomplish this job. ADS-B aviation technology would replace radar eventually as the primary method of surveillance for separation of aircraft and monitoring of Air Traffic Control (ATC).  

Regulations mandating ADS-B technology have been published by the US and some other countries, on aircraft flying in their regions based on differing schedules. Some countries which do not require ADS-B equipment yet have designated special airspace and routes to the aircraft that voluntarily equip.  

The ADS-B Out technology allows ground vehicles and equipped aircraft to broadcast their altitude, position, velocity, and identification to ATC and other aircraft. ADS-B In technology enables aircraft to receive such information.   

ADS-B aircraft technology provides important information that helps prevent and project traffic conflicts.

Key Advantages of ADS-B Aviation Technology 

  • Expanding ATC surveillance to more regions 
  • Increasing the efficiency and capacity of airspace 

Working of ADS-B Aviation Technology 

In the US, vehicles and airplanes equipped with ADS-B exchange information on either of two frequencies – 1090 MHz or 978 MHz. Traffic Collision and Avoidance Systems (TCAS) and Mode S and A/C transponders use 1090 MHz. The message elements of Mode S are extended by ADS-B, adding information about an aircraft as well as its position. The extended squitter is referred to as 1090ES. 1090ES was chosen as the global standard for ADS-B by an international technical advisory committee.  

The FAA is upgrading and deploying ground networks systematically. ADS-B Out can be attained in the US through two methods. The first method is using next generation of transponders that operate on the band of 1090 MHz. The second method is making use of a new technology known as Universal Access Transceiver (UAT). UAT works on 978 MHz and is applicable to aircraft flying below 18,000 feet in the US.  

In the US, as per the ADS-B mandate, all airplanes must have ADS-B Out installed in them by January 1, 2020.  

Equipment Needed for ADS-B Aviation Technology 

Depending on how old your aircraft is, the equipment may be complex or simple. Moreover, some elements might already be on your aircraft. The ADS-B system would need at least one WAAS-capable GPS receiver connected to the transponders directly. The transponders will require upgradation to be compliant.  

ADS-B Out Technology 

The broadcast portion of ADS-B technology is referred to as ADS-B OutADS-B Out equipped airplanes will transmit aircraft information continuously, like location, altitude, and airspeed to the ADS-B ground stations. The minimum necessary equipment for ADS-B Out flight technology is an ADS-B-approved transmitter – a 1090 MHz Mode S transponder or 978 MHz UAT to be used with a Mode S or Mode C transponder installed previously. 

ADS-B In Technology 

The system’s receiver part is referred to as ADS-B In. Aircraft equipped with ADS-B In can receive and interpret the ADS-B Out data of other participating aircraft on an Electronic Flight Bag or a computer screen. The function of ADS-B In needs an approved system of ADS-B Out as well as an ADS-B receiver with “in” ability. Furthermore, for graphic traffic and weather displays, a display interface compatible with ADS-B will be required. 


Wrap Up 

ADS-B aviation technology helps provide airspace users with a more accurate traffic understanding. It’s a highly useful technology helping optimize aircraft performance. If you are an aircraft owner in the United States, get ADS-B flight tracker system installed in your airplane promptly.
