摘要

使用GIPSY和伯尔尼GPS软件包的应用程序和扩展,在德国物理技术中心(PTB)的一个大地测量接收器和美国国家航空航天局的两个大地测量接收器之间处理载波相位GPS观测。他们的结果与双向卫星时频传输(TWSTFT)数据进行了比较。研究发现,在存在接收机仪器延迟的情况下,消除日边界效应的算法需要谨慎处理。根据所选择的方法,不同的解决方案类型之间可能产生几个毫秒的时间差和高达100 ps/天的频率差

GPS Carrier Phase Analysis Noise on the USNO-PTB Baselines
Carrier phase GPS observations between a geodetic receiver at the Physikalisch-Technische Bundesanstalt (PTB) and two geodetic receivers at the USNO are processed using applications and extensions of the GIPSY and Bernese GPS software packages. Their results are compared with two way satellite time and frequency transfer (TWSTFT) data. It is found that algorithms that eliminate day-boundary effects require careful handling in the presence of receiver instrumental delays. Depending upon the approach chosen, time differences of several ns and frequency differences of up to 100 ps/day can develop between solution types
