All,

    On the apogee contact we noticed that the ACE had gone through a reset. The reset occurred on 19 Jan 23 @16:57:30 GMT. I performed the following standing CAR’s: “ACE Reset recovery” and the “Disable Spin Pulse Protect”. During the pass the ACS FDC was reenabled, the Static Z was set, the spin pulse protect was disabled and the Kalman filter input was set back to STA_PCT_Valild. The spin pulse looked nominal. The sun maneuver was nominal. Razor # I100 714 ACE Reset 19 Jan 2023
