Mapping terrestrial UHF interference from orbit
Between 2019 and 2023, students and faculty at the Budapest University of Technology and Economics (BME) launched four PocketQubes that became benchmarks for picosatellite reliability and scientific return[1]:
| Spacecraft | Size | Launch | Orbit & primary achievement |
|---|---|---|---|
| SMOG-P (MO-105) | 1P | 6 Dec 2019 (Electron) | Deployed at ; produced the first global 3D map of terrestrial DVB-T television interference in the UHF amateur band before decaying in September 2020[2]. |
| ATL-1 (MO-106) | 2P | 6 Dec 2019 (Electron) | Tested ceramic thermal-insulator materials in orbit alongside the BME spectrum monitor; re-entered in October 2020. |
| SMOG-1 (MO-110) | 1P | 22 Mar 2021 (Soyuz-2.1a / UniSat-7) | Higher-altitude () sibling of SMOG-P with polyimide structural panels; operated for years in orbit[3]. |
| MRC-100 | 3P | 12 Jun 2023 (Falcon 9 Transporter-8) | multi-band spectrum monitor ( to ) with active attitude control and S-band downlink. |
Cold redundancy inside a 50 mm cube
Despite the volume of a , SMOG-P and SMOG-1 duplicated the power channels, on-board computers and UHF transceivers in a cold-redundant architecture switched by a supervisory controller, proving that single-point-failure tolerance is achievable at [1].
