 Basically what I was thinking about was mostly the tracking of things, but I wanted to build a protocol in a way that the groundstations stay compatible for a deployment stage that enables them to send. This will surely not be the case for a while but still i'd like to think ahead. The main idea was that this kind of frame can be received and sent to the groundstation. For communication among groundstations over a satellite at least some kind of from adress field needs to be added.
