RINEX

Receiver Independent Exchange Format ( RINEX ) is a receiver- independent data storage and exchange format. It is used for GPS or GNSS raw common nowadays, so in particular for pseudorange code measurements and carrier phase observations and satellite ephemeris. The availability of these data allows a subsequent reevaluation mostly for the determination of position solutions of higher accuracy. This format was an important prerequisite for the development of scientific analysis programs for the analysis of GNSS data. RINEX is supported by many manufacturers of GNSS satellite receivers.

A first RINEX format description was published in 1989 by the Astronomical Institute of the University of Bern. The format of 3.0 was published in 2006 ( Version 3.01 of 2009).
