This year 38c3 mission control assigned c3space a premium landing zone, right next important ground support facilities, such the info desk and heaven. Shortly after touching down late on day 0, our mission specialists started deploying power and IEEE 802.3 compatible communications infrastructure.

During day 1 those capabilities were expanded to also include a VHF/UHF Transceiver with an omnidirectional antenna.

Note that we made sure to use incandescent lights when add seasonally appropriate decoration to our antennas, to avoid degrading our receiver performance. We promptly proceeded to utilize those capabilities to very successfully participate in a local toilet related communication exercise.

To allow for medium bandwidth communication, a dedicated wired link to c3isdn was installed to be used for ISDN based communication. A transmitter and receiver unit for Fax data was connected, to facilitate the legally binding exchange of our most important scientific datasets.

Of course there was a wide variety of space hardware on display at the assembly again.

There were two engineering models of the PICOBUS deployer, a Qubik PocketQube, the SIDLOC Spacecraft Identification and Localization payload, an engineering model of PHASMA, a SatNOGS-COMMS module and last but not least a working model of Curium.

Too keep track of the satellites that are actually in space, we once again used our SatNOGS monitor setup that we build for 36c3.

Besides our assembly there were also multiple talks at the congress, that might be of interest for space enthusiasts:

Hacking yourself a satellite - recovering BEESAT-1 Easily one of the most impressive talks of 38c3. The first official space privateer PistonMiner, tells the daunting tale of achieving remote code execution and ultimately patching the firmware, on a satellite that was presumed lost years ago.

An open-source guide to the galaxy: Our journey with Ariane 6 Paul and Manthos tell the story of two space missions, starting with sourcing a launch opportunity all the way to the final integration onto the rocket at the spaceport in French Guiana.

Euclid, das Weltraumteleskop - 180 Millionen Galaxien sind ein guter Anfang A talk about the first year of operation for Euclid a new space base telescope. Curious tales of moisture on mirrors and how accidentally x-ray your spacecraft. While the talk is in German there are English subtitles and audio tracks available.

Investigating the Iridium Satellite Network Technical deep dive into the newer protocol extensions used on the Iridium satellite network. This talk also contains a bit of SDR know-how and tips on how to listen to satellite constellations at scale.

Geostationäre Satelliten als Hobby A quick introduction on all kinds of fun that a hacker can have with geostationary satellites. Keeping track of accidental TV broadcasts and satellite radio pirates can quickly turn into a whole new hobby.

We had a lot of fun at the congress and we hope to see everyone again at the 39c3.
