Sistem Auto Tracking Payload Dual Axis

Abstract

In observing atmospheric data in the field of aerospace , there is a need for a device to observe atmospheric conditions. One of the required tools is a balloon as known as balloon sonde. Auto tracking is to follow the direction and movement of radiosonde in order to align the antenna and radiosonde. The way how to follow the direction of the balloon is to communicate between the two devices. The data acquired from experiment is balloon positins consisting of langitude, latitude and altitude data wich will be further processed into the movement of pitch angle and yaw. From the analisys, this experiment shown the actual results of the tracker had average percentage of 15% error but does not affect the antenna because beam width reaches 20 degrees. The advantage of this device is it can beat 10 km radius when tracking.
