Microcomputer-controlled closed-loop system for positioning radio telescope
Abstract
A millimeter range radio telescope is used to track and observe stars that emit radiation at radio frequencies. The horizontal system responsible for moving the principal receiving plane is equipped with servo systems for controlling the azimuthal position and pitch of the telescope. The telescope contains six servos which employ closed loop computer controlled positioners or automatic tracking and focusing. In order to match the servo systems to the basic requirements of the closed loop computer positioning system, a microprocessor based controller was designed and tested in experiments on the control of servo systems for regulating the principal and auxiliary planes of the telescope. Methods were studied for coordinating and correcting the system. This work is briefly described.
