An versatile and modular Electrical Ground Support Equipment (EGSE) system has been developed using Artificial Intelligence (AI) techniques to control and test the PESCA instrument and the communication process with the satellite without any human supervision. The PESCA instrument has been designed and built with the purpose of studying the Solar Energetic Particles and the Anomalous Cosmic Rays. It will be part of the Russian PHOTON satellite payload that is scheduled to launch in December of 2005. The tool allows complete and autonomous control, verification and validation of the PESCA instrument, although its modularity makes it extensible to other on-boards instruments.
