ABSTRACT:
A system and method for GPS acquisition in relatively high interference is described. Acquisition is aided by an Advanced Tightly Coupled (ATC) tracking filters that compute a satellite range residuals and range rate residuals for satellites being acquired. Multiple channels are used in parallel to search for the desired satellites. Range residuals from the ATC filters are used to correct the computed receiver offset and thus allow acquisition in the presence of relatively high interference.
