Abstract
A method and system for reducing Global Navigation Satellite System (GNSS) carrier tracking loop ambiguities comprising: receiving a plurality of GNSS satellite signals with a first antenna in operable communication with a first tracking device and a second antenna in communication with a second tracking device in at least one GNSS receiver; and sharing of data between the first tracking device and the second tracking device. The sharing is configured to facilitate a commonality in a carrier phase derived in the first and second tracking devices. The sharing also results in a cancellation of the commonality when a difference phase is formed between a carrier phase from the first tracking device and a carrier phase from the second tracking device.
