Bringing space closer to home.

Mission

The FramSat mission is a satellite platform to demonstrate bleeding-edge Norwegian technology and space systems, and consists of two satellites: FramSat-1 and FramSat-1.5. FramSat is Orbit NTNU's first partner mission, where we've developed a satellite bus and integrated an experimental sun sensor developed by EIDEL AS and UIO for testing in space conditions, funded by NTNU and the Norwegian Space Agency. By developing our own in-house systems on volunteer hours, we are in a unique position to launch payloads that would not be affordable on commercial options.

Specifications

FramSat-1 is a 1U nanosatellite measuring about 10x10x10 cm and weighing approximately 1.3 kilograms. The satellite is designed, assembled, programmed and tested by students at Orbit NTNU, with invaluable support from our sponsors and partners. FramSat-1 operates in the UHF radio band in a Sun-Synchronous Orbit at an altitude of 560km

Launch

On September 6. 2026 20:12 UTC, ISAR Aerospace launched Spectrum 2 from Andøya Spaceport to space. With FramSat-1 on board, ISAR and Orbit NTNU became historic in participating in the first successful orbital launch from Norway and European mainland.

Signals

FramSat-1 was successfully deployed from the Spectrum 2nd stage, and deployed its antennas ~30 minutes after deployment. Using NTNU's UHF antenna located at Gløshaugen, Trondheim, Orbit NTNU was able to receive FramSat-1's first signals already about 3 hours after ignition of Spectrum at 23:22 UTC.
