ADS-B stands for Automated Dependent Surveillance Broadcast and is part of the NextGen Air Traffic system, which has now installed across much of the U.S. An ADS-B transponder installed in your aircraft will transmit its altitude, airspeed and location to air traffic control ground stations via GPS signal.
The FAA has required that all aircraft flying in air traffic controlled airspace must be equipped with at least ADS-B Out by January 1, 2020.
ADS-B Out, as the name implies, transmits data “out” from the equipped aircraft. Some ADS-B units can also receive data, called ADS-B In. If your aircraft is equipped with ADS-B In, you will be able receive data (altitude, airspeed and location) from aircraft in your vicinity and have it displayed in your cockpit or on a portable device, such as a tablet or smartphone. This can be a real boon to traffic avoidance with the capability to “see” other ADS-B equipped aircraft in real time.
Another benefit of ADS-B In is the ability to receive graphical weather information. With ADS-B, pilots receive the same data into the cockpit the same information ATC is receiving in real time – adding a higher degree of situation awareness and improved safety.
