Paper Abstract

For a long time, various types of satellites, especially remote sensing satellites, can be used to meet not only the needs of earth observation, such as the observation of land and ocean resources, atmosphere and environment, etc., but also the needs of human exploration from outer space. Facing with the frequent occurrence of the global natural disasters and man-made accidents, human beings needs urgently a new satellite system with the rapidly responsive and sensing capacity. In this paper, the satellite application mechanism of the software defined radio (SDR) technology is studied, and a new concept of multifunctional satellite system with the rapid event response is proposed. A single satellite integrates three or more functions such as remote sensing, communication and data transmission, etc. The switching time between functions in one satellite is better than 300 s. Satellites can be adapted to different orbits of GEO, MEO and LEO. According to different application requirements, several satellites which have the same or different functions can form a satellite system. This new multifunctional satellite system can meet not only the need of rapid response of natural disasters such as earthquake and meteorological disasters, but also requirements of remote sensing, communication and data transmission for the man-made disasters such as the search and rescue of missing aircrafts, conflagrations, etc.
