Error Pointing Correction System Implemented in the Air Balloon Communication System

Abstract

In this study the design of WLAN-based communication systems will be carried out, which consists of various devices assembled into a payload to be flown in air balloons, communication will be carried out to connect balloons at a frequency of 5.18GHz and for communication between balloons and system users. working at 2.4GHz frequency, after the balloon has been flown successfully, one of the problems that will arise is the movement of the balloon on the azimuth axis which will affect the level of received power by the receiving balloon (second balloon), because this will make the automation system to correct the position of the antenna in the transmitter balloon and receiver balloon to return to the position, from the system that has been running shows an error in the error pointing correction system, the minimum error is 0 degrees which means there is no error, while the biggest deviation is 0.858 or equal to 0, 3 dBm is utilized, the deviation is 0.476% the amount of power received by the receiving antenna drops to 73.015% of the maximum value (LOS) at a measured distance, after the automation system works the value goes back to 99.84%.
