Abstract
The disclosure generally relates to position sensors, and more particularly to repair of carrier-phase cycle slips using displacement data. An apparatus for use in position sensing may include a displacement sensor, a positioning signal receiver, a memory, and a processor coupled to the displacement sensor, the positioning signal receiver, and the memory. The processor and memory may be configured to processor and memory are configured to detect a loss of lock of a first carrier tracking loop associated with the first set of carrier-phase measurements, wherein the first carrier tracking loop is associated with a first integer ambiguity, estimate, based on the displacement data, an ambiguity increment to the first integer ambiguity subsequent to the detected loss of lock, and resolve a second integer ambiguity associated with the second set of positioning signals based on the first integer ambiguity and the estimated ambiguity increment.
