ABSTRACT
This chapter introduces spacecraft system engineering, composition, and presents classification of spacecraft systems, and the significance, general principles, and special requirements of spacecraft system design from a system engineering perspective. The upper level of a spacecraft system is space engineering system. To perform its functions, the spacecraft must be launched by a vehicle at the launch site first, and then the ground-based TT&C system will perform TT&C on the launch vehicle and the spacecraft, making sure the spacecraft enters a predetermined orbit. Therefore, in addition to spacecraft system, the space engineering system also consists of the carrier system that pushes the spacecraft into orbit, the launch site that is used for the final assembly, testing, refueling and launch for launch vehicles and the spacecraft before launch. The goal of spacecraft system design is to obtain an optimized “new” spacecraft system that meets the specific mission requirements.
