The table below provides the list of events affecting the RA2 mission, during the ENVISAT lifetime: 1 March 2002 - 8 April 2012.

 

  Generic mission or RA2 instrument event
  RA2 Instrument unavailability*
  Payload/Platform unavailability*
  Transition to YSM**

 

* Instrument/Payload/Platform unavailablities started to be referenced in 2004 (reference as EN-UNA in Description column)

* *Does not correspond to a RA2 instrument unavailability, but the Service Module has been switched down to YSM (Yaw Steering Mode) instead of nominal SYSM (Stellar Yaw Steering Mode). This could cause degradation in the geolocation.
