Modular Attitude Determination and Control System for Small Satellites

In order to meet the cost goals of small satellites, attitude determination and control problems must be solved using standardized components. Small satellite attitude control systems must feature performance, versatility, and above all, low cost Large, custom designed, high cost attitude control systems have no place in the small satellite community. A modular concept of attitude control is presented which will allow ambitious performance and cost goals to be attained. Basic building blocks allow mission specific goals to be reached with a minimum of effort and expense. Several basic modules are described and applied to a number of representative mission requirements. The concept illustrates a philosophy of modularity, flexibility, and manufacturability so necessary to the small satellite community.
