Description |
| 11/13/2008 | 17:38:00 | | Disable yaw, roll, pitch reasonableness tests in control and non-control SCP. |
| 08/19/2008 | 00:33:00 | | Disables gas and automatic thruster firing. |
| 08/18/2008 | 18:15:00 | | 4 miscompares, ARRTLM Val=1 AMIMSWIN Val=1 AMIMUON1 Val=1 AMIMUON2 Val=0. A thruster unload was executed by the spacecraft. Additional control logic enabled in case of a close approach with debris from the Chineses Sat. Onboard s/w initated the thruster pulse (+ pitch) when the momentum threshold was exceeded. During the + pitch thruster firing the ROLL reasonableness test failed on the NON control side, which caused the MIMU to switch from MIMU 2 to MIMU 1, and set MIMU switching to INHIBIT. |
| 08/18/2008 | 09:30:00 | | Enables Auto Thruster Firings |
| 01/25/2006 | 12:00:00 | PTC 1A | Pitch torquer coil inactive while spacecraft Z-momentum (pitch) transitions from a positive value range to a negative value range (while Z-Rwheel does the exactly the opposite). Considered rare but not anomalous. |
| 11/03/2005 | 12:00:00 | PTC 1A | Pitch torquer coil inactive while spacecraft Z-momentum (pitch) transitions from a negative value range to a positive value range (while Z-Rwheel does the exactly the opposite). Considered rare but not anomalous. Transition complete on 18 Nov 05. |
| 05/27/2005 | 18:50:00 | | End reduced gyro test. COmmand ADACS back to nominal mode using all gyro axisÆ. |
| 05/27/2005 | 17:07:00 | | Reduced gyro test, estimate pitch. Knockout out pitch gyro for 1 rev. |
| 05/25/2005 | 14:20:00 | | New ephemeris loaded to control OBP. |
| 05/23/2005 | 13:00:00 | | Attitude control commanded to NOMINAL mode (from YGC). |
| 05/22/2005 | 19:45:00 | | Subtracted 3 full seconds from command clock because of drift. |
| 05/22/2005 | 19:40:00 | | First on-orbit ephemeris upload to N18 spacecraft, nominal execution. |
| 05/21/2005 | 12:20:00 | ESA | ESA to nominal algorythm. Spacecraft remains in YGC attitude control mode. |
