Monitoring Rosetta's New Avionics Software
In the reporting period (23 July to 30 July 2004) the spacecraft was monitored daily to ensure thecorrect behaviour of its avionics systems after the upload and activation of the new version 7 of the on-board software. Taking the opportunity of this period of daily contact a number of tests were carried out, which in turn served as confidence checks of the functionality of the new software:
The TC files containing the patch commands for the redundant avionics processors have been uplinked to the on-board mass memory. The patch of the redundant processors to the new software version 7 is planned for the beginning of August. At the end of the last New Norcia pass in the reporting period (DOY 212) Rosetta was at 71.9 million kilometres from the Earth. The one-way signal travel time was 3 minutes 59 seconds.
