Abstract

In this paper, the development and technical features of Micro-small Satellite are introduced. According to the functional requirements and restricted conditions, the Attitude and Orbit Control System (AOCS) is designed for one occultation sounding satellite constellation. In the design of AOCS, the Integrated Electronic System (IES) based on the integrated electronic technology is realized, which consists of many hardware function modules and software function modules, and some miniaturized products are adopted such as micro star tracker and Micro-Electro-Mechanical System (MEMS) Gyro. By the dynamics features of the occultation sounding satellite constellation, a dynamics simulation system is designed to test the AOCS at the same time. According to the result of simulation, it can be known that the AOCS based on the integrated electronic technology satisfies preferably the strict requirements of the occultation sounding satellite constellation.
