The high-altitude balloon calibration solar cell is the standard cell which can be used for the ground sun simulator and light detection. This paper presents a control method of sun tracking for solar cell calibration at a high altitude by the flying Balloons. The paper gives the design of hardware and software of the solar tracking, hybrid automatic tracking control strategy, altitude tracking control problem solving, and the result of solar tracking in high-altitude simulation environment test. Mearwhile, the key technical problems in the high-altitude ballon calibration solar cell tracking control system under extreme environment is solved, such as reliability, continuous tracking and anti-shake in extreme environments. In the experiment, the balloon flight level is 32 km, flying time is more than 2 h, and the deviation of solar tracking is less than 1°. A preliminary analysis shows that the results of solar calibration test are reasonable and reliable, which provides a new idea for the study of high-altitude balloon AM0 solar cell calibration with sun tracking control method.
