Orbit and ATTITUDE FILES

There are four types of auxiliary orbit files

  • (Recommended) Long Term Predictive Orbit File covering at least 3 years with a 10 minutes time step in GSE (PRED-ORBIT-LT-GSE) and J2000 (PRED-ORBIT-LT-J2000) coordinates in OEM format,
  • Daily Measured Orbit File (MEAS-ORBIT) containing position and velocity attitude in Common Data Format (CDF),
  • Monthly Predictive Ephemeris Data (PRED-ORBIT-GSE or PRED-ORBIT-J2000) in OEM format, at 1 second time resolution in OEM format,
  • Predictive Orbit Element File (ORBIT-ELEM) is also provided in XML format.

There are four auxiliary attitude files

  • Predictive spacecraft Attitude File (PRED-ATT) in CDF, 
  • Predictive Payload Attitude File (PRED-PAYLOAD-ATT) in CDF, 
  • Daily Measured Attitude File (MEAS-ATT) for the spacecraft in CDF,
  • Daily Measured Payload Attitude File (MEAS-PAYLOAD-ATT) in CDF

OTHER AUXILIARY FILES

  • Time-lag between on-ground clock and on-board clock, provided in XML format (CLOCK-DIFF)
  • List of telecommands uploaded to the spacecraft, in XML format (TChistory)
