Orbcomm is a satellite provider focusing on Internet of Things (IoT) data. They collect and distribute short messages from small terminals all over the world, like shipping containers, vehicle trackers, remote sensors, etc. Since these satellites are on VHF frequencies right next to the NOAA weather satellites, I can pick them up with my existing QFH antenna.
The actual data you can see from these isn't super interesting, since everything is encrypted. All you can really get is the satellite position and some basic telemetry in cleartext. It's still kind of neat to be able to say you did it!
I used this software to decode the signals: github.com/fbieberly/ORBCOMM-...
