Abstract

A highly accurate mechanical control for the antenna reflector is necessary for the Multi-Beam Satellite Communication System (MBSCS). This paper describes the design, development and experimental performance of the antenna pointing mechanism (APM) for the MBSCS. The mechanical configuration and component performance of the mechanism is documented along with the launch and operational environments of the three-axis communications satellite. This model which is based on nonlubricated direct-drive actuators is particularly appropriate for the APM's requirements. These include compact size, low mass, high stiffness, low power consumption and high reliability.
