REACH RS2 RINEX File Format

Hi Harrison,

Sorry for the delayed response!

You can use the raw data log recorded in UBX format to convert it to .obs and .nav files via the RTKConv app.

.21B is an SBAS broadcast data file. .21P is a mixed GNSS navigation message file. You can find out more information about the RINEX formats in its official documentation like this one.
