Micro-core is one general module of satellite, and its function density is very high. A new idea and a new concept are adopted to design micro-core. Aiming at attitude determination system (ADS) of micro-core, this paper adopts an optimization design method to determine parameters of sensors. In aspect of selecting sensors of attitude determine system, the optimization method adopted in this paper is greatly different from traditional methods, and realization of this method has important effects on design of micro-core and even on micro-satellite in the future. This paper selects both ADS based on star sensor and fiber-optic gyroscope (FOG) combination and ADS only based on star sensor as ADS of micro-core, and adopts extended Kalman filter (EKF) to estimate attitudes. This paper sets up optimization model of ADS, and adopts optimization method to determine parameters of star-sensor and FOG, and then optimization results are achieved, and finally are validated. By analyzing results, the optimization method is proved to be feasible and valid.
