RinexObsFile Object

Description

The RinexObsFile object provides functionalities for reading and writing PseudorangeObservation data (C1, C2, P1, P2) to and from a Rinex Observation file. This is an ASCII file of Pseudorange data conforming to the RINEX standard. The time system is GPS Time, and the scalar pseudorange data is given in meters and is reference frame independent.
