Mechanism Health Check & PMD ADC Calibration History

The health status of the APSM and NDFM mechanism has to be checked on a regular basis (once/month until February 2003, bimonthly since March 2003). This is accomplished by running a pre-defined procedure at FOCC which actuates these mechanisms. The pass/fail analysis of the checks occurs automatically on-board.

In addition to this activity, a PMD ADC calibration is required

  • not later than 30 days after the last mode transition from STANDBY to HEATER, or
  • in case of indications of a SEU event

    • The PMD ADC calibration is also triggered at FOCC by a pre-defined procedure, usually once/month. In case an anomaly has transferred SCIAMACHY to STANDBY, this procedure can be omitted. Both APSM/NDFM health check and PMD ADC calibration are executed in the eclipse phase of the orbit. The table below provides

  • ABS_ORB
    		•  number of orbit when activity has been executed
  • UTC
    		•  UTC time when activity has started
  • Result
    		•  check success indicator for APSM/NDFM health check

    PMD ADC entries marked by a '*' indicate an instrument switch-off (planned or anomaly) which 'replaced' the regular calibration.
