Abstract:	One of the latest applications in GPS is the E911 call service for wireless phones. In this case current GPS navigation accuracy meets the FCC requirements but the hardware size and power consumption of GPS are issued for implementation. The software GPS receiver could be the solution. In this paper a GPS signal processing algorithm for software GPS receiver is developed. The IF signal is sampled directly from the RF chip and all the other processing including signal acquisition, tracking, making TDOA(Time difference of arrival) measurement aided by reference station information, and solving the navigation solution are implemented in software using signal processing techniques. The simulations and experiments with real GPS data are performed to validate the proposed algorithm.
