Automatic Antenna Positioner

This well-designed, LM3S801-based system autonomously points an antenna (base station) toward a target (remote transceiver) indicated by a latitude-longitude pair. The microcontroller reads the quadrature encoder signal from the motor and the current antenna heading from the sensor. It then processes the data and sends the PWM result to a motor driver.
