No. 24 - Software Verification Complete
Final tests carried out in this period were:
- Further Navigation Cameras test, including slews with the cameras in tracking mode
- Redundant RTU Payload Core and the redundant Solar Array Drive electronics
1 August
On 2 and 3 August the loaded command files for processors 2 and 3 patching were executed. Memory dumps and comparisons with the ground software images confirmed the correct patching of the redundant processors with the new on-board avionics software v7.
The OSIRIS instrument was activated manually during the New Norcia pass on 4 August, to support data generation and retrieval tests which were carried out on the following day remotely from the PI's home institute.
