The following mode dependent values are valid Star Tracker Usage. For LRM/SAR/SARin: 0 = No Star Tracker data used for product generation and attitude initialisation done by using default values from the IPFDB; 4 = Star Tracker data used for product generation and these data are the same used by the satellite through its AOCS (Attitude Orbit Control System). For FDM: 0 = No Star Tracker data used for product generation and attitude initialisation done by using default values from the IPFDB; 1 = Data of Star Tracker 1 used for product generation; 2 = Data of Star Tracker 2 used for product generation; 3 = Data of Star Tracker 3 used for product generation
