Abstract

The invention relates to a strapdown inertial / satellite integrated navigation detecting system and a simulation testing method thereof. The system comprises a strapdown inertial subsystem, a satellite navigation subsystem, a navigation module and a control and display module, wherein the control and display module is connected with the strapdown inertial subsystem and the satellite navigation subsystem respectively to transmit track information; the strapdown inertial subsystem and the satellite navigation subsystem are respectively connected with the navigation module to transmit angular speed, accelerated speed and satellite signals; the output end of the navigation module is connected with the control and display module to feed an integrated navigation result back to the control and display module to form a closed-loop system. The system has real error characteristics. According to the system, optional tracks can be generated and do not need to be carried by actual carriers, so that the research and development cycle of an integrated navigation system is shortened, and the research and development cost is reduced; the real-time dynamic simulation on carrier movement according to a preset track can be realized and finished, and the universality is very strong.
