Patent ID: 7605749

Claim:
A system, comprising: one or more global satellite navigation system (GNSS) receivers having a plurality of antenna inputs; a plurality of multi-frequency antennas respectively connected to the plurality of antenna inputs through transmission paths; and a common clock reference for processing phase information from different ones of the antennas for a plurality of GNSS frequencies in response to an estimate of delays associated with the transmission paths for at least one of the GNSS frequencies, wherein the estimate of delays includes a measure of a phase delay in the transmission paths for two or more of the GNSS frequencies, the phase delay being used in a determination of position information for the antennas by the one or more receivers; wherein at least one of the receivers resolves integer cycle ambiguities for a pair of the antennas in carrier signals at the GNSS frequencies by comparing a residual function derived from carrier phase measurements and the measure of the phase delay in the transmission paths for the two or more of the GNSS frequencies for a plurality of possible integer combinations.
