Abstract :
Aimed at the shortcomings of China´s Beidou Double-star active positioning system, a new passive positioning algorithm is proposed. According to the data collected from two synchronous satellites, as well as atomic clock and altitude gauge carried by a user, passive positioning is achieved through grid search algorithm. Simulation results of the algorithm show that the method is fast and accuracy enough for real-time positioning. It is a practical way to improve the Beidou Double-star positioning system
