(NPLI) using a GNSS Common-view time transfer. As can be seen from Fig. 5, the IRNWT was again seen to be traceable to UTC (NPLI) with an offset not exceeding 10 ns (2-sigma) over … WebCommon view time transfer using the GPS system was developed by NIST researchers and is illustrated below. Here the time difference between two clocks, A and B, is determined by simultaneous observation of a third …

WebApr 1, 2015 · For common-view, the maximum distance to the ground is roughly 6000 km. Ground to ground time transfer depends very significantly on the visibility of the satellite. In common-view mode, the space oscillator is only solicited over the time interval of laser pulses (typically between 0.1 s to a few seconds). WebGPS common-view time and frequency transfer service.
