Claim Text:
1. A positioning system 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, which positioning system comprises: 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; 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; 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; said computer system being configured for applying a position offset corresponding to an offset between differential corrections created by said master base and said secondary base stations; said rover being configured for: transitioning from the coverage area of one said base station to the coverage area of the other said base station; and transmitting said position offset to said rover; and said computer system being configured for correcting said rover GNSS-defined positioning with said position offset.
