ISDC End of Revolution Report (CONS)
CONSOLIDATED REVOLUTION 2688
— Report of October 04, 2023
Perigee Passage at start : 2023-09-19T14:25:22
Perigee Passage at end : 2023-09-22T06:15:55
Remarks:
--------
a) In relation to the AHF for Rev 2688, which has just been completed, we should draw your attention to the following:
- Due to operator error, the routine automatic jobs were not scheduled on the FDS before the start of the revolution.
In particular, the routine updateslew jobs were missing that correct any attitude drift after the previous open-loop
slew by updating the slew parameters for the following slew.
- This oversight was only spotted and corrected at 2023-09-20T06:20Z during PREQ 26880023.
- In particular, after the first slew in the revolution (amplitude 80 degrees), there was an off-pointing
from the planned attitude of:
-0.0162957 deg in RA
-0.1393327 deg in Dec
which would normally have been corrected with the second OSL to the same attitude.
In this case, the attitude error between realised and planned attitude evolved over the next 21 pointings to:
0.0451930 deg in RA
-0.1743808 deg in Dec
before the correction was made during PREQ 26880023.
- After a brief discussion with Jutta, we realised that this unfortunate oversight has a couple of positive points,
namely:
- it shows the general robustness of the Gyro Slew on-board software, in that the attitude drift increased very
slowly after the first large slew.
- it increased our optimism that the gyro slew s/w would provide good performance should we use it to slew
to an earth-occulted attitude for a planned earth occultation attitude in the future.
- We hope that the impact on science processing is small, but would be interested in any feedback from ISDC.
