The TriSat satellite series comprises three CubeSat-type nanosatellites developed by the University of Maribor and the company SkyLabs in Slovenia with the support of the European Space Agency (ESA). The satellites support the education of students at the University of Maribor, explore the radiation environment around Earth, and test new spaceflight technologies.[1][2]
Satellites
[edit]The first spacecraft of the series, TriSat, was launched to low Earth orbit in September 2020[3] Vega flight VV16 together with another Slovenian satellite named Nemo HD, as the first two space missions of Slovenia.[4] The satellite was testing a miniaturized multispectral optical payload for Earth observation in short wave infrared spectrum and high-throughput S-BAND communication equipment.[2] Due to high solar activity, the satellite de-orbited a year earlier than planned – on 29 September 2024.[5]
The second spacecraft, TriSat-R, was launched to medium Earth orbit in July 2022 on Vega-C.[6][7] It carried a radiation measuring instrument developed in cooperation with CERN that was used for studying ionizing radiation in the environment of the Van Allen Belts.[8] TriSat-R also tested a miniaturized camera, only 2 mm across, which successfully took a picture of Earth from 6,000 km away.[9]
The third spacecraft, TriSat-S, is awaiting launch on Isar Aerospace's Spectrum rocket, expected in 2026. It was designed to test battery hibernation technologies and miniaturized imaging-based navigation.[2][10][11]
