ROSETTA-ORBITER CHECK GIADA 2 EAR3 EARTHSWINGBY3 V1.0

Payload Checkout 10 (PC10) was an active checkout where a target independent opportunity to perform interactive operations and to request spacecraft pointing was given to all Rosetta payload teams. All Rosetta payload took part in this scenario The Active Payload Checkout 10 ran for 12 consecutive days starting on the 21th September 2009 until the 2th October 2009. This is the allocated time of the active PC10 scenario that preceded it PC10 consists of two phases. The 1st phase is a passive test (GD01) similar to the previous Passive Payload Checkouts the 2nd phase is an active test; GD02 is dealt with GIADA/VIRTIS interference test, in GD03 we upload on-board of new Context File settings performing and checking new procedures, GD_INT is dealt with GIADA/ROSINA interference test. The passive test (GD01), which includes standard procedures and full functional verification, was executed by switching on Main and Redundant I/Fs in sequence and executing similar procedures for the two cases. GD02, GD03 and GD_INT were executed only on Main I/F. The data reported in this data set have been converted from ADC counts to engineering values. The quality of the Housekeeping and Calibration data is good. Scientific data are due to noise, as no grain event is expected during this mission phase. These data must be only considered to evaluate GIADA behaviour and not as real scientific data. Data reported by GDS and IS are due to noise as no dust event is expected during this mission phase. MBS frequency changes, once normalised for frequency vs. temperature dependence, if present, are due to deposition of contaminants existing in the S/C environment. Housekeeping and Calibration data from all GIADA sub-systems are useful to evaluate instrument health and behaviour when compared with similar data acquired during other mission phases.
