Several new radiation belt models have been recently released, including the NASA AP-9/AE-9 models. Large differences are apparent and before adoption, the models’ characteristics and quality needs investigating. In addition valuable data sets are emerging from European radiation instruments that should be included and compared so that a consistent harmonised model set is established. The current standard radiation models date from the early 1980s and are based on datasets from the 1970s and 1960s. Recently the AP-9/AE-9 radiation belt models have been released with significantly different characteristics and are based on a significantly greater quantity of data. Preliminary investigations of these new models are showing significant differences with the ECSS standard models for some standard orbits. During this activity, all new models will be subjected to a detailed validation exercise against in-situ datasets including but not limited to ESA and other European spacecraft and other radiation environment models. Systems for the use of these new models for both long term radiation effects (e.g. dose, non-ionising dose, solar cell degradation and human effects) and shorter term radiation effects (e.g. internal charging, instrument noise, Single Event Effects) will be developed and established in a form compatible with any updating of ECSS-E-ST-10-04C. Procurement Policy: C(3) = Activity restricted to SMEs & R&D Entities.
