| 抄録 | GPS common-view method was developed in the 1980s and it had been a world leading time transfer technology in the recent two decades. According to this method, daily averaged time comparison precisions obtained from the C/A code single channel receivers could reach 10(exp -14) approximately. However, to meet the advancement of atomic clocks, it is attempted to develop new methods for highly precise time comparison technology. This paper describes a fundamental theory of the GPS common-view method, data analysis and error sources as well as to express the improvements of the time transfer precision using multi-channel receivers, the improvements of satellite orbit, of the ionosphere model, and carrier phase observations. Especially, the evaluation results of multi-channel receivers and the ionosphere model improvements of recently observed data are shown. |
