Dynamic positioning precision acceptance test method for Beidou second-generation positioning system

The invention discloses a dynamic positioning precision acceptance test method for a Beidou second-generation positioning system. The method achieves the dynamic precision measurement and acceptance testing of the Beidou second-generation positioning system on a high-speed dynamic target through combining with a rocket sled testing method. The method mainly comprises the steps: fixing a Beidou second-generation positioning system receiver on the rocket sled, and starting the rocket sled; recording the rocket sled at the frame frequency of 100,000 frames per second through stare-type high-speedphotographing optical measurement equipment disposed at an outer side of a rocket sled rail; calculating the movement position information of the Beidou second-generation positioning system receiveraccording to a geodetic surveying result of the stare-type high-speed photographing optical measurement equipment, the position of the Beidou second-generation positioning system receiver on the rocket sled and the recording i
