Hello,
I am a big fan of your work and I’m trying to partially reproduce it. I use Lovable.dev (I saw your advertisement to recruit developers; this software could help you) and would like to add other options. I am particularly interested in telemetry data and TLEs (historical). I am sending you a draft preview of what I’m doing : https://satellite-sentinel-archive.lovable.app/.
Best regards,
Telemetry data can be found in https://db.satnogs.org/api/telemetry/ and for some of them there are decoders to use to decode them.
For the historical TLE, while we keep them, they are not currently exposed, there is a plan to do so but low in priority.
