The problem of preprocessing of observations and navigational data files in the format RINEX 2.10 is considered. The polynomial data processing on a full time period of observation and on a driving window of the fixed size is used. It is offered outcomes of processing to introduce in the format GMF (General Measurement's Format). The features of the program RNXParser are discussed. The example of its applying is given.
