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_v2.1.pdf. The high rate data supplied in this file includes L1 and L2 full phase, L1 phase model and L1 and L2 SNRs.

An example data file (with simulated data) can be found here.
