A few things I have noticed with the new medet_arm:
- It appears to require write permissions on the soft-bit files. I’m not sure if this has always been the case, but it was the result of some interesting errors during some debugging.
- To decode Meteor M2-2, medet_arm needs the -diff option added to the command line. This is a bit of a problem, as it means the process_meteor.py script needs to know what satellite is being observed. Unfortunately, this is not something that can be passed through (according to what I’m seeing in satnogs-client here: https://gitlab.com/librespacefoundation/satnogs/satnogs-client/blob/master/satnogsclient/observer/observer.py#L225 ). There is an option to pass through the entirety of the TLE, from which we can extract the satellite number, but it’s going to be a bit of a pain.
So for now, the meteor decoder script is not going to work correctly with the new Meteor sat. I’m not sure when/if I’ll have the time to modify the scripts to deal with this.
