Abstract The high-altitude detection technology uses sounding balloons to bring the detector into the high-altitude measurement,but the recovery of the detector has the problem of too large search range.After designing the sounding balloon and establishing the falling point prediction model of the ball borne device,this paper compares it with the actual case of launching the sounding balloon to explore the enforceability of the design and model.By putting the prediction model into practice,the azimuth error is 4.2% and the radial distance error is 1.4%,which greatly reduces the search range and the difficulty of equipment recovery.
