Abstract
Processing a Global Navigation Satellite System (GNSS) signal that is received at a receiver includes, e.g., initializing a carrier phase of a local carrier signal for a current epoch and based on a first Doppler estimate, in which the first Doppler estimate is derived from a measurement gathered in a previous epoch. The carrier phase then is updated repeatedly for the current epoch while the GNSS signal is mixed with the local carrier signal. Updating the carrier phase relies on second Doppler estimates, which are based on inertial measurements made at the receiver. Using the inertial measurements can, in some cases, negative effects of dynamic motion associated with coherent integration.
