An Oslo rooftop, about 80 watts, and a hand-aimed antenna were enough to reach orbit.

The satellite, named OPS-SAT PRETTY and flying under the ESA’s OPS-SAT Space Lab program for outside experiments, ran the game in an experiment punningly called PRETTY DOOMed. Doom ran on a different satellite , the OPS-SAT-1, in 2023, but this time is different, as the game was launched with a voice command.
The radio club sending the command in question is LA4O, of the Norwegian Radio Relay League, hams transmitting as part of the experiment. The club’s signal went over 1296 MHz narrowband FM at about 80 W, indicated, using an Icom IC-9700 radio and a Wimo helix antenna at 15.1 dBi, directed by hand. As for the voice, Run 6, the morning pass, used a looped synthesized voice from a keyer, with three of six captures detecting the command. Run 7, the evening pass, used a live operator at a microphone, with one of five usable captures detecting it.
The live operator’s command was “LIMA ALFA FOUR OSCAR, PRETTY PLAY DOOM DOOM DOOM, PRETTY PLAY DOOM DOOM DOOM.” The call sign is for legal identification.
On board the satellite, the voice is transcribed by a 27 MB quantized English speech-recognition model, picked because it could fit the satellite’s limited computer. The voice was handled by software-defined radio (SDR), which was able to narrow in on the voice and demodulate the source for the speech model. Tuning and demodulating a signal is usually handled by fixed circuits, but using software has the advantage of being mutable with an uploaded update. The voice used this time “was only the test signal,” project lead Georges Labrèche said, and the same setup could handle other things with a new model.
