Accuracy/Latency of the Position in GNSS’s RF Signal Aided by INS for ADS-B Out’s Requirement

Reza Dehmohseni

Abstract:	Using space based Global Navigation Satellite Systems (GNSS) technology, flying equipment can broadcast location continually (at 1Hz) to any ADSB capable device receiver and the Air Traffic Control (ATC) terminals. The USA’s FAA program office is changing the nation's air traffic control system from one that relies on radar technology to a system that uses precise location data from the global satellite network (not all radars will be discontinued). ADS-B Out technology has new requirements for aircrafts, drone, etc. in order to use the public airspace. Those technical requirements are: Latency, Source Integrity Level (*SIL) and System Design Assurance (**SDA). See FAA Advisory Circular 20 document AC-165A sections: 3-1c. Tests for measuring “accuracy” of the GNSS signal and “uncompensated latency” of the position solution is discussed.
