12. Radiation detectors for small satellites

Simeon Ivanov (Space Fluent LTD)

Oral presentation

Ionizing radiation measurements of primary and secondary sources on small satellites is currently limited to a very small number of detector types with poor energy resolution and timing characteristics and very limited geometry. SF develops a modular system that overcomes these limitations within the technological constraints of the small satellite platform and deliver high performance...

Oral presentation

ASTRA-LEO (Advanced Spaceborne Telescope for Radiation Analysis in Low Earth Orbit) is a multi-particle radiation detector currently being developed by the Centre for Space Sensors and Systems (CENSSS) at the University of Oslo and integrated into the CENSSAT-1 CubeSat, scheduled for launch in 2027. The instrument is designed to detect Solar Energetic Particles (SEPs), observe Gamma-Ray Bursts...

23. SpacePix Chip Evolution for Space Dosimetry - VZLUSAT-2 Flight Results and SpacePix3 Lab Characterization

Radek Novotný

11/06/2025, 12:40

Oral presentation

We present the results from the space mission VZLUSAT-2, where our novel space dosimetry system based on the SpacePix2 chip was successfully tested in orbit. The detector system operated continuously over an extended period, demonstrating stable performance in low Earth orbit and providing valuable data on the space radiation environment. The system’s ability to distinguish between different...
