Patent ID: 8362951

Claim:
A method to determine location, the method comprising: following a search discontinuity, integrating, by a mobile station, at least one observable signal metric of a satellite positioning system signal for a time T 2 ; sampling, by the mobile station, the integrated at least one observable signal metric at a time T 1 , where the time T 1 is shorter than the time T 2 ; identifying, by the mobile station, peaks of the at least one observable signal metric subsequent to the sampling at the time T 1 and before the time T 2 has elapsed; solving, by the mobile station, for a common code phase offset based on the identified peaks; selecting, by the mobile station, a location determination mode based, at least in part, on the solved common code phase offset; and determining, by the mobile station, the location based, at least in part, on the integrated at least one observable metric of the satellite positioning system signal, integrated for the time T 2 , and the selected location determination mode.
