ADSB-Out (1090MHz) Targets with a Bearing

ADSB-Out uses a modern transmission technique which is automatic in that it requires no pilot or external input and is dependant in that it depends on data from the aircraft's GPS system. The advantage of ADSB-Out automatically (continuously) broadcasting its GPS location is that it is easily detected and its unique position can be plotted on a screen. Additionally, an accurate voice alert can be given similar to that given by an air traffic controller. That is, Bearing, Height Separation and Distance. Importantly with ADSB-Out this information is provided continuously and with greater accuracy when plotted on a screen. (An Air Traffic Controller can only describe it’s bearing in relation to the hours on a clock face. This is the true position with an error of up to +/- 15 degrees).

PilotAware uses the smaller of the two antennas provided to receive ADSB-Out signals.
