A final assignment research has been carried out entitled " Two Axes Antenna Tracker Controller With Close Loop Control System Method". The background of this research is to maintain communication between tracking antennas with payload that are flown so that data transmission can run well. The aim of this study is to be able to move the antenna according to input in the form of azimuth and elevation values derived from the PC and sensor. The method used in this study is by comparing the input value from the PC and the input value from the sensor to find out the error value, to see how much the deviation of antenna detector from the payload. This error will be used by the controller as the input value to drive the motor. The detector antenna movement is a driver, where the driver works according to the instructions received from the microcontroller. The microcontroller determines when the motor must rotate to right or left and to rotate up or down. The results show that the motor can rotate vertically and horizontally based on the input received. The azimuth motor takes 1 minute and 6 seconds to rotate at CCW direction and 1 minute and 5 seconds to rotate at CW direction when rotating 360°. Motor elevation takes 50 seconds and 53 seconds to rotates up and down when rotating 360°. The average of error value in azimuth motor movement is 0% and the average of error value in motor elevation movement is 1%.
