[CFOSAT] Safe Hold Mode and maneuvers
CFOSAT switched to Safe Hold Mode in May 2025 due to the loss of a gyroscope.
With only three gyroscopes functioning (six at takeoff), the attitude control mode had to change. The biggest impact was on maneuver performance.
This is why CFOSAT went off course for several months. In collaboration with our Chinese (CNSA/NSOAS) partners, the CNES CFOSAT project team planned a series of maneuvers, and the satellite is now nearly in its nominal orbit. Please note that all products processed during this period are considered nominal.
