With the characteristic of active positioning, the Beidou double-star navigation and positioning system is not appropriate for military applications. In order to overcome the shortcomings, a new passive positioning algorithm is proposed. According to the data collected from the 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 provides a new practical algorithm to improve the Beidou double-star positioning system.
