Description
The Norwegian Radiation Monitor (NORM) is a compact, single particle-telescope-based radiation monitor developed for measuring energetic electrons and protons in space environment. NORM has been designed as an easily adaptable space radiation monitor for satellite missions in GEO, LEO, and HEO.
The first NORM unit, flying aboard the Arctic Satellite Broadband Mission (ASBM), provides critical information on the space radiation environment along its three-apogee (TAP), 16-hour highly elliptical orbit (HEO). A review and an evaluation of the available NORM measurements of trapped electrons and solar proton radiation is presented. We demonstrate the inter-consistency of NORM data relative to the unit’s calibration, as well as of the derived flux products with third-party measurements. It is shown that NORM provides high-quality, high-resolution measurements of the dynamic electron fluxes within the 0.4–6 MeV energy range - as the satellite crosses the outer electron belt - and high-quality proton fluxes within the 10–90 MeV energy range during Solar Proton Events. ASBM/NORM dataset provides an invaluable asset for updating space radiation environment models and for space weather monitoring.
This work has been implemented by NORM Exploitation and Utilization System (NEXUS) project supported by the EC-DEFIS/2024/OP/0012 contract between European Commission, Directorate-General for Defence Industry and Space and IDEAS-SPARC.
