In order to reduce the workload and improve the emergency response speed in space launch mission landing area, a rocket wreckage recovery system needs to be built, which uses the global satellite navigation technology to achieve real-time self-positioning of the falling wreckage, and calculates the landing point quickly and accurately through a simplified applicable model, so the work can be completed efficiently. Taking the real-time position and velocity information of the wreckage as input, and considering air resistance, a dynamic model based on the real-time location information of the rocket wreckage is proposed to calculate the predicted landing point. Based on the measured self-positioning data from the rocket wreckage falling experiment, the accuracy of the model is verified and the calculation result is ideal, which shows that the model is accurate and effective, and it can be popularized and applied to predict the rocket landing point on the basis of accurate ballistic measurement data.
