XRapS

The XRapS application was designed to be a program to process offline baselines that were observed with GPS and in the rapid-static mode. For the processing of baselines you need always a reference site.

It is possible to have more than one reference stations in a project but in this case you have to compute the baselines for the several reference sites successively. Besides the processing of the observations and some graphical features you have a simple tool for coordinate transformation.

A network adjustment is not included. Besides RINEX-data the binary data format of a couple of manufactures of GPS-equipment could be directly loaded and processed.

You will need GPS observation data on both frequencies L1 and L2 to resolve the ambiguities and to compute coordinates with cm-accuracy. Moreover, there must be valid phase observations on L1 and L2 and valid observations of one code to at least 5 satellites available. If pure L1-data will be processed, only a code solution is available. The maximum sampling rate is 2 Hz or 0.5 seconds.
