Continuous time transmission method based on Beidou No.3 PPP-B2b information

A continuous time transmission method based on Beidou No.3 PPP-B2b information comprises the following steps: S1, if observation data is continuous, PPP calculation is carried out by using the Beidou No.3 PPP-B2b information, and a time transmission result is obtained; and S2, if the observation data is instantaneously interrupted due to the abnormal observation data, using a clock error result predicted by historical clock error data of a receiver as a time transmission result of the current epoch. According to the method, high-precision time transfer can be realized under the condition of no internet support, meanwhile, the condition of transient signal interruption caused by shielding and instantaneous interference is considered, the re-convergence speed of PPP is accelerated by utilizing a mode of modeling a receiver clock, continuous time transfer is realized, and the time transfer efficiency is improved. The application range of the GNSS precise time service/time transfer technology in the national defe
