An optimum system design and an engine operation optimization are described in the case of an ion engine application for north-south stationkeeping of a synchronous communication statellite. The optimum design analysis which allows determination of the necessary ion engine operating conditions to yield the lightest possible system to perform N-S stationkeeping is presented. The engine characteristics are modelled and identified by the experimental data, then the daily thrust period about nodal points and the engine net-accelerating voltage are optimized for the lightest system design. Moreover, an on-line computer steady-state optimization technique to keep optimum operating conditions under system component characteristic changes in the environment is presented.
