Movinganalysis of Integrated Symmetrical Concectrated based on geosynchronous orbit

Integrated Symmetrical Concentrated (ISC) system presented by NASA is a concentrator Space Solar Power Station(SSPS), which has the advantage of high photovoltaic-electricity converting efficiency. However, in order to capture the sunlight with maximum, the system requires the concentrator to keep the sun-tracking during all the orbit traveling time. For this reason, the ISC model is built, and planning of postures is proposed according to its working feature in this paper, and the moving theoretical analysis is given by means of the relationship between rotation angle and time, which can provide the certain reference for the adjustment on the primary mirror.
