Embodiment Construction
[0022] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:
[0023] The technical characteristics of the embodiment of the present invention are: firstly, it solves the technical bottleneck of the carrier phase in the application of the satellite two-way time transfer system - the consistency control of the code and the carrier phase at the satellite exit. Secondly, the carrier phase measurement is applied to the satellite two-way time transfer system. Compared with the code pseudo-range satellite two-way time transfer method, its accuracy is improved by 1 to 2 orders of magnitude. The implementation of this method is based on the following conditions: 1. a satellite; 2. at least two user stations, and the basebands of the two user stations can realize the calculation of the code and carrier phase adjustment amount, and the baseband control part transmits the baseband signal according to the calculation result The code and...
