Space Packet Diff

[ahotasu]

Another issue I have frequently encountered with spacecraft/instrument integration is validation of data that is routed multiple ways through the spacecraft--real time Telemetry Source Packets are packaged and transferred differently from those that are stored on the (virtual) recorder for later playback. SORCE suffered an obscure problem where the playback data were occasionally messed up and we did not catch that in I&T because we only focused on the real-time data. For later missions, I wrote a 'diff' program as part of my Perl utilities that took two data files, parsed them, and then looked for differences, which could be munged bits/bytes or data that are only available in one of the two files.

This could be a completely separate tool from SPP, but could use SPP to do the parsing.
