Abstract:
GPS (Global Positioning System) satellite clock corrections are computed from observational data and final GPS satellite ephemerides and are typically available 3 to 6 days after the observations are made. The clock corrections can be applied to pseudo-range (code) measurements from a single receiver and can obtain positioning accuracy at the one metre level depending on the GPS receiver characteristics. The corrections are archived in ASCII format at 30-second intervals and can be interpolated (e.g. one second data) without degrading positioning accuracies.Used with the GPSPACE GPS point positioning program and the Precise GPS Satellite Ephemerides, to provide Differential Global Positioning System (DGPS) accuracies without requiring base station data.
