Atmospheric occultation data in a somewhat complicated but general custom binary format. This data file contains all high rate atmospheric data sent us by the GNSS receiver on the LEO.

A simple perl reader for this format can be found here:

The format is described in the document GNSS_High_Rate_Binary_Format_v1.9.pdf. The high rate data supplied in this file includes L1 and L2 full phase, L1 phase model and L1 and L2 SNRs.
