The Satellite Risk and Radiation Forecast System (SaRIF)
Abstract
With thousands of new satellites due to be launched, the exploitation of low and medium Earth orbit and the introduction of electric propulsion to reach geostationary orbit there is a growing need to develop space weather services to protect satellites from space weather. Here we present the new satellite risk and radiation forecast system (SaRIF) which is designed to address this need. The system integrates the radiation environment with radiation effects on spacecraft. It uses the BAS radiation belt model (BAS-RBM) to forecast the electron flux throughout the outer radiation belt up to 24 hours ahead. The flux is used to calculate deep dielectric charging, dose rate and total ionizing dose behind levels of shielding. The results are compared against European and NASA design standards and presented as risk indicators for satellites in medium, geostationary and slot region orbits. The forecasts are updated every hour and are available with forecasts issued by the Met Office Space Weather Operations Centre (MOSWOC). The system includes post event reconstruction to aide anomaly resolution and an archive of data that can be displayed graphically. The system is available via the European Space Agency Space Weather web portal.
