GPS共视法定时参数的研究

Research on Timing Parameters for GPS Common-view Method

叙述利用GPS共视法进行时间比对时,标准数据格式(GGTTS)中各个参数的意义和实现方法。目前国际上各时间频率传递研究机构统一采用这种标准格式,各研究机构之间可方便地进行各地原子时标的比对。作者根据该格式编制了共视法软件,实现了GPS数据的接收和处理。

With the common-view method of the satellites of the Global Positioning System(GPS) for time comparison, the definitions and their realization method for these parameters in the Group on GPS Time Transfer Standards (GGTTS) GPS data format are explained. At present, this standardization is worldwide used by the research institutes of time and frequency standards, which makes the comparison of the atomic time standards in the world more conveniently. According to the format, the common-view software is developed, with which the GPS data can be received and processed.
