Using space internet to implement spacecraft automatic operation and control

Abstract

In order to resolve the problems of the operating mission being more complex, the servicing range being wider, the demand of air - space - ground TT&C (Tracking, Telemetry and Control) being stronger and stronger in the future, the idea of automatic operation and control for spacecraft based on space internet is proposed. The architecture and operating flow for integrated space - ground TT&C network are designed, simultaneously. The key techniques needed to study for implement automatic operation and control are discussed, finally. The idea of automatic operation and control for spacecraft is to share the data resource through the space internet. The cooperated work of multi-system and multi-mission is implemented by means of TT&C mission integrated scheduling technique. The integrated space - ground TT&C network is composed of GEO/MEO /LEO spacecraft, constellation and ground TT&C network. The purpose of space - ground united TT&C is to save ground TT&C resource. The key techniques include: the integrated planning technique of TT&C mission, the centralizing scheduling technique for mission operating center, the conflict automatic inspect technique, the managing technique for inter-satellite link. The researching production will be applied to enhance the level of mission planning and to reduce the dependent on ground TT&C station in the future. © 2012 by the American Institute of Aeronautics and Astronautics, Inc.
