Research on the Precision Time Benchmarking Method of a Manned Spacecraft Rendezvous and Docking

In the process of rendezvous and docking aircraft more comprehensive testing, in order to achieve the aircraft to work more, ground test equipment need to have a unified, high precision standard of time, as a reference test data, test instruction. In the test process, the time interval of the system should be adjusted to ensure the accuracy and consistency of time. Therefore, it is necessary to study the accurate method and system of high precision time, and ensure that the equipment function and precision can meet the test requirements.
