The Extended RINEX Format
Extended RINEX is an extension of the standard RINEX 2.x format defined by ARL:UT. It defines derived data that can be associated with satellite under track at each epoch. Two major types of Extended RINEX types are topocentric coordinates azimuth and elevation, and differences, such as the widelane difference.
The list of available extended Rinex obs types:
