Open Sourcing Satellite Telemetry

Launched in 1978, the International Sun/Earth Explorer 3 was sent on a mission to explore the Earth’s interaction with the sun. Several years later, the spacecraft changed its name to the International Cometary Explorer, sent off to explore orbiting ice balls, and return to Earth earlier this year. Talking to that spacecraft was a huge undertaking, with crowdfunding campaigns, excursions to Arecibo, and mountains of work from a team spanning the globe. Commanding the thrusters onboard the satellite didn’t work – there was no pressure in the tanks – but still the ICE mission continues, and one of the lead radio gurus on the team has put up the telemetry parser/display crafted for the reboot project up on Github.

The guy behind the backend for the ICE/ISEE reboot project should be well-known to Hackaday readers. He’s the guy who came up with a Software Defined Radio source block for a cheap USB TV tuner, waking everyone up to the SDR game. He’s also played air traffic controller by sitting out near an airport with a laptop, and has given talks at Black Hat and DEFCON.

The ICE/ISEE-3 telemetry parser/display allows anyone to listen to the recorded telemetry frames from the satellite, check out what was actually going on, and learn how to communicate with a device without a computer that’s rapidly approaching from millions of miles away. He’s even put some telemetry recordings up on the Internet to practice.

Although the ICE/ISEE-3 reboot project will have to wait another decade or two until the probe makes its way back to our neck of the woods, [Balint] is taking it in stride an organizing a few Software Defined Radio meetups in the San Fransisco area. He just had the first meetup (Video below) where talks ranging from creating a stereo FM transmitter in GNU radio, a visual introduction to DSP for SDR and SETI signals from the Allen Telescope Array were discussed. There will be another meetup in a few weeks at Noisbridge, with some very cool subjects on the roster.

  1. Hey Brian or Mike – regarding your “We’re hiring” post, any chance you could confirm receipt of the applications?

    I realize you’re probably buried in responses, but E-mails with links (as requested) might cause some to be flagged as spam and be inadvertently put into your spam folder.

    Can you let us know if our applications were received?

      1. Thanks.

        BTW, I’ve noticed that you and Mike (as appropriate) will actually answer questions on the blog here. Such as Mike’s response on the contest thread.

        I really appreciate that – it gives a sense of community. Even if I’m not the one in the conversation, it feels like I’m among people, listening in. Keep up the good work!
