The satellite selection algorithm is important when using integrated navigation equipment to estimate position. Selecting part of all visible satellites will limit the number of channels and reduce processing time. By analyzing the principle of quasi-optimal satellite selection algorithm, an improved weighted quasi-optimal satellite selection algorithm was proposed. The main idea of this algorithm is calculating value of all visible satellite using the unit user-satellite vectors and ranging errors. In each iterate, the satellite with the highest importance value is selected to the assistant satellite set. The simulation results show that, the proposed algorithm costs less time with simple calculation by comparision with other satellite selection algorithms. The proposed algorithm satisfies the requirements of integrated navigation receivers.
