Abstract:
1. A method of determining a position of a device having wireless networking capability, the method including: providing information from a wireless local area network (WLAN) to supplement global positioning system (GPS) information to better perform the determining, wherein the information from the WLAN includes decoded GPS data, a current time, and a recent position provided one of via and by the WLAN; using the information from the WLAN, computing a first GPS satellite having a highest elevation angle from a set of GPS satellites; searching for the first GPS satellite with multiple correlators, wherein searching includes partitioning the multiple correlators into correlator pairs including an in-phase correlator and a quadrature-phase correlator; and after acquiring the first GPS satellite, partitioning the multiple correlators into tracking sets, each set including the in-phase correlator, the quadrature-phase correlator, and one of an in-phase early/late correlator and a quadrature early/late correlator.
