Development of computation software named Multi-Utility Spacecraft Charging Analysis Tool (MUSCAT) started in November 2004 as one of the provision. The simulation code will be used for a PEO (Polar Earth Orbit) satellite as well as for a GEO (Geostationary Orbit) satellite or a low inclination LEO (Low Earth Orbit) satellite. The development includes four major parts: development of the GUI (Graphical User Interface), development of the solver, acceleration of computing speed, and code validation. The beta version of MUSCAT was released in March 2006 as the first integrated software. The integrated GUI tool, called 'Vineyard' provides integrated development environment on local PC. The solver includes fundamental physical models necessary for charging analyses at LEO, GEO and PEO. Parallelization improved the computation speed and controlled iteration time reduced total time of computation. Experiments for the fundamental code validation were also carried out and the results showed good agreement with the numerical analysis. In the paper, development of the numerical solver is described., 資料番号: AA0063154014, レポート番号: JAXA-SP-06-010}, pages = {71--76}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {Multi-Utility Spacecraft Charging Analysis Tool(MUSCAT)の帯電解析エンジンの概要}, volume = {JAXA-SP-06-010}, year = {2006} }
