摘要

The rapid growth, preducted in space communications stimulated dieas beyond present soutions. In addition to geosynchronous satellites, which presently carry nearly all space transponders in use, new low and intermediate orbit constellations ofsatellites and even constellations in eccentric orbits are in design and planning. The paper gives an overview of this scenario to derive the new and challenging requirements on the satellites attitude and orbit control system (AOCS) and presents solutions, based on examples from current projects. For the first time, commerical AOCS have to be produced in series and the technologies employed are driven equally by performance, quality and effort (cost and schedule). with the high number of satellites, to be operated simultaneously in constellations, on=board autonomy with minimum ground intervention during operation becomes a ,,must``. This concerns nomial operation as well as rconfiguration and repair in cse of faioures. Now methods for autonomous failure management, and autonomous orbit determination and station keeping are therefore a central subject of the paper.
