Patent ID: 8370064

Claim:
A system for navigation and tracking, comprising: an inertial navigation system adapted to generate a replica GNSS signal; a global navigation satellite system, wherein the global navigation satellite system comprises: a module to digitize a GNSS signal received from a constellation of global navigation satellites; a correlator to receive the digitized received GNSS signal and to receive the replica GNSS signal from the inertial navigation system, wherein the correlator correlates the received GNSS signal to the replica GNSS signal to generate a correlated GNSS signal; a coherent integration module to coherently integrate the correlated GNSS signal from the correlator to generate an integrated signal having a predetermined rate, wherein the predetermined rate is a function of at least receiver clock performance of the inertial navigation system and the global navigation satellite system; a filter to receive the integrated signal and to generate a data signal for navigation and tracking; and an output device to present navigation and tracking information based on the data signal, to provide guidance for a vehicle or to track a target.
