Satellite Attitude Dynamics Simulation and Control,

Abstract

The Satellite Attitude Dynamics Simulation and Control System (SADSaC) project has two main objectives. The first is to provide a visual demonstration of satellite attitude dynamics. The second purpose is to be used as a learning tool by providing actuator hardware for student analysis aiid design. SAD SaC is a 22" cube attached to a bearing on a 3, pole that allows for near-frictionless rotation about the vertical axis. Attitude control will be done using a dual actuator system of a reaction wheel and gas jet thrusters. Tachometers and an absolute optical encoder will provide sensing capabilities of satellite position and satellite and reaction wheel velocities. This paper describes in detail the procedures used during design from conception to operation, as well as the modeling and system tests that were necessary to ensure proper operation. Documentation of engineering drawings, mathematical models and component parts ensure easy duplication of SADSaC should the need for more than one arise.
