Does ADS-B work on the ground?

ADS-B Out. ADS-B Out works by broadcasting information about an aircraft’s GPS location, altitude, ground speed and other data to ground stations and other aircraft, once per second. ADS-B ground stations are smaller and more adaptable than radar towers and can be placed in locations not possible with radar.

Where are ADS-B transponders required?

ADS-B is required in Class A, B and C airspace within U.S. domestic airspace and all land mass regions of the U.S. as defined in 14 CFR 1.1 and it includes the states (contiguous and non-contiguous), U.S. possessions, or territories.

Does ADS-B require line of sight?

The current ADS-B system relies on data from the Global Positioning System (GPS), or any other navigation system e.g. GLONASS, INS. The maximum range of the system is line-of-sight, this means typically 200 nautical miles (370 km), because of the Earth curvature.

What is an ADS-B transponder?

ADS-B allows equipped aircraft and ground vehicles to broadcast their identification, position, altitude and velocity to other aircraft and ATC. This is called ADS-B Out. Current transponders enable ATC and other aircraft to know your aircraft’s relative position and altitude.

Where are the ADS-B ground stations at airports?

The ADS-B antennas are mounted on cell towers if they’re not at airports. If you park where you can see the cell tower your receiver should pick up the transmission. I visited a tower nearby yesterday, and this is what it looks like. Excellent effort, John!

Which is better ADS-B or radar ground stations?

ADS-B ground stations are smaller and more adaptable than radar towers and can be placed in locations not possible with radar. With ground stations in place throughout the country, even in hard to reach areas, ADS-B provides better visibility regardless of the terrain or other obstacles.

What does it mean to build an ADS-B station?

Building an ADS-B station. ADS-B means Automatic Dependent Surveillance Broadcast, aircraft transmit in-flight data such as identification, position and speed. System benefits other airspace users, and enables ground folks to track airplanes. For more info on how the system works, watch this Youtube video, or read the Wikipedia entry.

What is ADS-B on the ground avionics?

Cover Story: ADS-B On The Ground – Avionics FAA’s NextGen program to modernize the National Airspace System (NAS) took a great leap forward in late August with the selection of an industry team led by ITT Corp. to provide the ground infrastructure of a nationwide Automatic Dependent Surveillance-Broadcast (ADS-B) network.
