eclayr retrieves automatically from servers configurable by the user the necessary reference and truth data for performance assessment, such as:

  • Truth reference for satellite ephemeris and clock biases (SP3-c files)
  • Truth reference for ionosphere and TGD values (IONEX files)
  • Broadcast ephemeris navigation data (RINEX files)
  • P1-C1 code biases (DCB files)
  • Satellites’ antennas phase center offsets (ANTEX)
  • Broadcast EGNOS messages (EDAS/EMS format) for automatic EGNOS performance analyses
