초록

If the release point of the precision air delivery system is determined only by L/D, target accuracy can be greatly reduced due to changes in wind speed and direction by altitude. In this paper, after conducting a self-made precision air delivery system (PADS) drop test, we analyzed the problems that may occur due to wind changes by altitude and proposed an algorithm to determine the release point of PADS to increase the precision of PADS landing. As a result of conducting the simulation with this algorithm, it was similar to the results of the drop experiment. In addition, the conceptual design of HW and SW was carried out for the actual dropsonde implementation in the future.
