POSITION DETERMINING – DESCRIPTION AND OPERATION
GPS
The Global Positioning System consists of a receiver and an antenna.
The GPS receiver is embodied within the GNS 430W/530W: it provides precise position, velocity,
and time measurements for enroute, terminal and non-precision approaches. The position, velocity,
and time determinations are computed by the receiver based on satellite signals provided by the
Global Positioning System (GPS) satellite constellation.
