Description
Summary:The predicted rapid growth in space communications has stimulated many ideas beyond today's solutions. In addition to geosynchronous satellites, new low and intermediate orbit constellations of satellites and even constellations in eccentric orbits are being designed and planned. The paper gives an overview of the new and challenging requirements for satellite attitude and orbit control systems (AOCS), and presents solutions based on examples from current projects. New methods for autonomous failure management, autonomous orbit determination and station keeping are discussed.
