Satellite & Stations Clocks

RINEX clocks files

RINEX Clock files contain the solutions for station receiver and satellite clocks. The solutions consist of the offsets due to clock synchronisation errors and contains the receiver clock offset estimated in the clock reference frame as well as the offsets for the satellite clocks including relativistic clock corrections. In addition to the offsets, the drifts and accelerations for the clocks may also be provided, although only the offset is mandatory. Together with each of these values the standard deviation must also be provided.

Most common sampling rate for clock data is 30s and 5 mins although other sampling rates are also possible. RINEX clock files are extremely important in POD and Genaral Relativity tests.

The GSSC is able to ingest all existing versions of the RINEX clock Standard (see a complete list of versions past and present here). as ‘Resource Format’ for the ‘Station Clock Products’ resource type.
