Research on the positioning accuracy of high speed rocket skid with Beidou receiver

Beidou system and inertial navigation system in the existing laboratory conditions can not simultaneously simulate acceleration, velocity and vibration conditions, proposed ground high-speed the sled technology to achieve dynamic navigation system space position, velocity and time parameters calibration technique. Here focus on the structure and precision analysis of the composition of the test system, these technical means to ensure high-precision navigation system under conditions close to the use of the environment to test its accuracy. This test can be implemented navigation system product design, manufacturing and delivery.
