A combined analytical and experimental program has been carried out to understand, simulate, and model the effects produced by the coupling of space electron induced electrostatic discharges (EID) into satellite structures. The program had five main tasks: to develop a worst case model for EID defined as a current source and to incorporate it into an SGEMP code for coupling analyses; to construct and electrically test a scale model (SCATSAT) of the P78-2 (SCATHA) spacecraft; to make a comparison between test results and model prediction; and to specify a strawman set of electrical test procedures for simulating the response of spacecraft to ESD for incorporation into a Spacecraft Charging Military Standard; to compare the internal response of the SCATSAT to two techniques simulating different aspects of the discharge, the arc itself and the blowoff electrons.
