Abstract:The Integrated Operation and Control System (IOCS) is an important system of the polarorbiting meteorological satellite ground application system. One of its main tasks is to plan the receiving tasks for multisatellite ground stations to ensure the complete acquisition of global data. When an antenna of a satellite ground station is abnormal or unavailable, if the data is still received according to the original task plan, it will directly lead to the incompleteness of global data. Therefore, it is necessary to research the antenna state prediction and its task replanning technology so as to timely discover and handle the antenna anomalies of the satellite ground station, reduce the risk of continuous multiorbit data receiving failure, and finally achieve the goal of improving the success rate of polarorbiting meteorological satellites’ data receiving. In this paper, an antenna state prediction method for the satellite ground station based on statistical analysis is designed, and the task replanning method with minimum change to subsequent system operation, easy implementation and recheckable results is studied.
