Abstract
A dynamic calibration technique of Beidou receiver based on rocket sled test was proposed. By expounding the dynamic calibration process, the standard trajectory establishment method of the rocket sled test, the receiver dynamic positioning and speed error assessment method, the traceability of the external measurement parameters of the rocket skid test and the uncertainty evaluation method of the calibration process, a metered traceable rocket sled test system was established, and the calibration results of the two receivers were analyzed. The results showed that the rocket sled test can effectively solve the high dynamic calibration problem of Beidou receiver, which has certain application value and expansion prospects.
