ANTENNA ROTATOR DESIGN AND CONTROL

This paper consists of design and development of rotator for antenna positioning according to the desired azimuth and elevation. The rotator is to have the capability to be manually controlled (press button switch) or software driven. It should incorporate safety stop switches as well as position and speed sensors in order to achieve smooth movement and correct stopping position. The basic principle needs to be studies are speed control using the microcontroller, exact angle of position movement, and stoppable motor can be done in time due to emergency cases. As larger load is applied to the device, the large inertia will need to be compensated to achieve a good dynamic. For position and speed regulation in antenna system, a DC motor will need to be used as the primary driver along with the appropriate in mechanical coupling. The appropriate and suitable rotator need to be chosen for better result in speed and position
