SUGL Ephemeris Files

These files in the ZIP archive links below are in RINEX format and contain GPS navigation data that have been processed as described in Dr. Liang Heng's thesis.

These files were derived from the IGS navigation data files which were then cross-compared to eliminate erroneous data.

However, these files have not all been manually validated and may still contain some incorrect information.

Below are links to annual ZIP archives of the RINEX-format GPS Ephemeris Files for the years 2007 - 2020.
