A system study for satellite operation and control in next generation

摘要

Ever since the first satellite, ETS-1, in 1975, 28 NASDA satellites in total have been launched. With regards to satellite operations, NASDA has developed realtime TLM/CMD processing systems which could be commonly used for different types of satellite. Presently the third generation system is operational. Meanwhile, the recent trend of satellite operations is becoming more complicated, for example, CCSDS-adapted Satellites are emerging and computer technology is developing quite rapidly. Moreover, NASDA's role in satellite operations is changing from mainly Satellite Bus operations to experimental/whole satellite missions operations. Considering these circumstances, NASDA has initiated a study for the next generation system which is suitable for operations of future satellites keeping in mind the following viewpoints: (1) demands from mission support; (2) trend of satellite design; and (3) progress of computer environment. This is an interim report of the study.
