GNSS RECEIVER WITH AN IMPROVED CAPABILITY TO RESOLVE SUB-CARRIER TRACKING AMBIGUITIES

摘要

A GNSS receiver and the associated method, for calculating an unbiased position and time measurement from a plurality of satellite positioning signals, the receiver comprising: - a plurality of circuits configured to receive positioning signals from a plurality of satellites in GNSS constellations, - a plurality of first and second signal processing channels configured for processing a first selection of said positioning signals and determining associated first pseudo ranges, - a computer logic, wherein: - the computer logic is configured to calculate the unbiased position and time measurement from pseudo ranges being determined from positioning signals originating from distinct satellites. A GNSS receiver further comprising a second computer logic configured to calculate a second unbiased position and time from the first position and time, and the second signal processing signals.
