首先，时钟A和GPS接收器被用于。尽管GPS主要是从GPS卫星的星历中推断出的导航，但从系统中，如果两个时钟在已知坐标A和B上进行时钟。A的位置，以及从接收到的GPS时间都在同一颗GPS卫星的共同视图中，接收器在这两个时钟站点可能会重合——解码来自同一颗卫星的时间不同，接收到的发送GPS时钟时间不同。通过ence（时钟A - GPS时间）。这个方法是减去收到的移民以时钟A和B至少两个网站,简单、准确(估计补偿传播延迟,有比约100 ns对GPS的准确测量时间的时差),2,但覆盖全球,在receiveclock B和时钟。当所有的错误的贡献只是模式,不需要其他数据,收益率接收机
Summary First, Clock A and a GPS receiver are used to Even though the GPS is primarily a navigation deduce from a GPS sate1 1 ite' s ephemeris, from system, if two clocks at known coordinates A and B clock .A's location, and from received GPS time are in common-view of a single GPS satellite, receivers at these two clock sites may coinciden- decoded from the same satellite, the time differtally receive transmitted GPS clock times. By ence (Clock A - GPS time). This method is the subtracting the received times of arrivals as measured by clocks A and B at the two sites while simplest and least accurate (estimated to be compensating for the propagation delays, one has better than about 100 ns with respect to GPS an accurate measure of the time difference between time),2 but has global coverage, is in the receiveclock A and clock B. When all of the error contributions are only mode, requires no other data, yields receiver
