Data Quality - Pointing Performance

SCIAMACHY's Line-of-Sight (LoS) pointing performance can be degraded due to spacecraft manoeuvres such as

If in one of the above cases the Sun Follower is used in that period, out-of-limit error messages might be obtained in the Report Format.

Data Quality History - Pointing (2008-2012)

The columns labelled ’ABS_ORB’ and ’UTC’ indicate the orbit number and the UTC start time of the event. Note that in the case of orbit manoeuvres with attitude mode changes the LoS pointing uncertainty will start earlier at the time when the nominal Stellar Yaw Steering Mode (SYSM) is no longer applicable. This can amount up to a few orbits.
