NORM – Space Radiation Monitor

Product Description


NORM is the Norwegian Radiation Monitor for measuring energetic charged particle radiation in space. Monitoring space radiation is important for reliable operation of satellites, and all human activities in space. NORM is designed as an easily adaptable space radiation monitor for satellite missions in GEO, LEO, and HEO.

NORM’s first use will be in the Arctic Satellite Broadband Mission (ASBM), a pair of broadband communication satellites providing coverage over the arctic, owned and operated by Space Norway. The satellites will fly in a highly elliptical three point apogee orbit (HEO-TAP), touching different domains in radiation environment. This provides a unique opportunity to validate existing and new radiation environment models


We would like to thank the Norwegian Defence Research Establishment (FFI) for their help with the mechanical structure and environmental analyses.

NORM is developed under ESA Contract (4000128542/19/NL/AS) with the support of the Norwegian Space Agency and Space Norway HEOSAT AS.
