Patent ID: 8803735

Claim:
A method for differentially computing a rover unit location in a differential Global Navigation Satellite System (GNSS) with a computer system including a processor connected to an input and an output, the method comprising the steps of: providing a master base station with a master base GNSS antenna, a master base GNSS receiver coupled to the base GNSS antenna and a master base communication system including a master base transmitter; providing a secondary base station with a secondary base GNSS antenna, a secondary base GNSS receiver coupled to the secondary base GNSS antenna and a secondary base communication system including a secondary base transmitter; providing a rover unit with a rover GNSS antenna, a rover GNSS receiver coupled to the rover GNSS antenna and a rover communication system connected to the computer system and including a rover receiver; generating with the computer system a position offset corresponding to an offset between differential corrections created by said master base and said secondary base stations; said rover transitioning from the coverage area of one said base station to the coverage area of the other said base station; transmitting said position offset to said rover; and correcting with the computer system said rover GNSS-defined positioning with said position offset.
