Simplified standard MEO/GEO tools for spacecraft charging

To develop a tool for the evaluation of surface electrostatic charging that can be used without specialized training and which guides user in making appropriate choices for GEO/MEO?. application.

A user-friendly tool will be developed using software components from the SPIS (Spacecraft plasma Interaction Software). It will include standard plasma environment, material property lists, and will alllow 3-d geometrical models to be created. The tool will allow for a high degree of automisation of parameters needed to make the code run but which do not reflect real phsical inputs, e.g. mesh resolution, particle weights, time-steps. The code will be extensively verified using available data. User and data interfaces will also be produced.
