For the goal of seamless indoor and outdoor location based services(LBS), a integrated navigation algorithm with both satellite location and WSN is put forward in this paper. This paper also design semi- physical simulation platform based on software receiver structure, which integrate GPS receiver and WSN nodes. Pseudorange observation data of global positioning system (GPS) and distance observation data of WSN are utilized to carry out positioning. Simulation results show that comparing with traditional GPS location algorithm, adaptation range is increased and positioning with less than four satellites is realized using the algorithm; and comparing with WSN location algorithm, the algorithm has a higher precision
