Abstract: To avoid the complexity caused by initial coordinate information as well as derivation and iterative calculation,an algebraic solution of GPS static equations is studied.Calculation is simplified by solving the pseudo-range equations directly,which plays a significant role in ensuring the calculation accuracy to improve pseudo-range calculation speed effectively.Simulation results support the validity and practicality of this algorithm.
