A new empirical model for Saturn’s radiation environment included in the TRAPPED framework

Missions are being studied to the systems of outer planets, including extended observation periods by local orbiters or possible landers, that require careful evaluation of the local radiation and plasma environment for design of both platform and science payload. Radiation impact potentially includes total cumulative doses, single event effects from short term enhancements and internal charging risk whilst plasma environments present risks of surface charging.
Under the ESA Project TRAPPED (Testbed for Radiation and Plasma Planetary Environments), a consortium comprising ONERA, IRAP, MPS and Academy of Athens has developed a flexible and easy-to-use environment model framework and related software for gas giant planet systems based on the wealth of data from visiting missions. Within this activity, derived specific models were developed for the Saturnian system. 
Here, we will present the TRAPPED framework and more particularly the new specification model for Saturn’s radiation environment. This empirical model based on the last version of Cassini data (LEMMS, CHEMS and INCA) provides electron, proton and water-group ion fluxes in the magnetosphere of Saturn.
