HALE (High Altitude Long Endurance) is one of the Unmanned Aerial Vehicle (UAV) designed to be able to fly at high altitudes for a long time to carry out missions such as monitoring and surveillance. One of the challenges in developing HALE so that it can fly for a long time is how to optimize the energy generated, so that the energy is sufficient to fly HALE according to its mission design. The problem that occurs is that sunlight is not always perpendicular to the surface of the solar panels placed on the upper surface of the HALE wing. Therefore, a solar tracker control system will be designed to control the roll angle of the aircraft, in such a way that the position of the solar panels on the wings can be oriented exactly perpendicular to the direction of the sun's rays. In this study, a strategy for implementing a solar tracker control system for HALE ITB 1:2 was developed to obtain the optimal angle during the mission. There are two strategies, the first is mode switching, where HALE carries out two separate and alternate missions, namely the initial mission to follow its trajectory with a tracker heading and to switch charging missions with a solar tracking system. The second strategy is simultaneous, where HALE will track heading with the solar tracker simultaneously. Based on the simulation results, switching mode strategy has a percentage increase in the amount of energy produced by 5.2% compared to the simultaneous strategy which only has an additional percentage of 2.2%.
