FramSat-1.5 is the second and last satellite in the FramSat mission, developed by Orbit NTNU as a spare and backup for FramSat-1. Like its predecessor, FramSat-1.5 is a 1U nanosatellite measuring around 10x10x10 cm and weighing approximately 1.3 kilograms. It has been designed, assembled, and tested by students at Orbit NTNU, with invaluable support from our sponsors and partners.
While FramSat-1.5 carries the same technical specifications as FramSat-1, its purpose is to ensure mission redundancy and continuity. If FramSat-1 encounters issues before or during flight, FramSat-1.5 can take its place to secure the success of the overall mission objectives. The satellite, therefore, acts as a safeguard for the technology demonstration and for the verification of the Eidsvoll Electronics AS sun sensor payload.
FramSat-1.5 operates in the UHF band at a frequency of 435.141 MHz (± Doppler) and is designed for an orbit of 500 km altitude in SSO, enabling reliable communication and mission performance. It uses the same communication system, operating system, and software as FramSat-1, ensuring consistent data handling and operational reliability across both spacecraft.
The satellite is scheduled for launch following FramSat-1, also from Andøya Spaceport aboard Isar Aerospace’s Spectrum rocket. This continued partnership contributes to the first series of orbital launches from European and Norwegian soil, marking an important milestone for Norway’s role in the global New Space industry.
FramSat-1.5 stands as a testament to Orbit NTNU’s commitment to reliability, precision, and learning through hands-on experience. By building and preparing a complete spare satellite, our team ensures that the FramSat mission remains robust and ready for success, while continuing to educate and inspire the next generation of Norwegian space engineers.
