“…To prove the feasibility of the monitoring paradigm with novelty detection we applied it to an already documented anomaly that the ESA satellite XMM‐Newton experienced in 2009 and checked when the novelty detection prototype would have been able to detect the anomaly. Here is an excerpt of the paper that describes the anomaly and measures taken by the FCT (fight control team) to cope with it (Pantaleoni et al 2010):…”

T he most widely extended approach for automatically detecting anomalous behavior in space operations is the use of out-of-limits (OOL) alarms. The OOL approach consists of defining an upper and lower threshold so that when a measurement goes above the upper limit or below the lower one, an alarm is triggered. Then engineers will inspect the parameter that is out of limits and determine whether it is an anomaly or not and decide which action to take (for example, run a procedure). This is the original outof-limits concept.The current OOL concept has evolved to cope with more situations such as distinguishing between soft and hard limits; for example, a soft OOL triggers a warning to pay attention, a hard OOL triggers an error that demands attention. Soft limits are contained within hard limits. In addition OOL thresholds (soft and hard) can be configured so that different thresholds are applicable in different situations (for example, depending on the working mode of a given instrument).

“…-delta-V manoeuvre to change the orbit, in early 2003 to improve the ground station coverage, -upgrade of the mission control system to SCOS-2000 in 2005 (9) , -change of the antenna handover strategy, due to a problem in the antenna switch in 2008 (11) , -tank1 and tank4 temperature control taken over by ground after a problem on a low temperature protection of the tank heater circuit, occurred in July 2009 for tank1 and in Nov 2010 for tank4 (10) . Besides the above changes in the operations baseline, no other major modifications were done to the original mission concept.…”
