How to Determine the TOM in GNSS's RF Signal for ADS-B Out’s Latency Requirement

Reza Dehmohseni

Abstract:	This paper, “How To Determine TOM (Time Of Measurement) in GNSS’s (Global Navigation Satellite System) RF (Radio Frequency) signal for ADS-B Out (Automatic Dependence Surveillance Broadcast) Latency requirement”, summarizes a technique for marking a point in time from which the position solution latency can be measured. The receiver’s hardware/software takes a finite amount of time to calculate position of its antenna and determine the location of its host vehicle in the WGS-84 coordinates which is the standard used in the FAA’s air traffic system. 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).
