Sounding rockets are the only direct detection method for near-space and are utilized for different kinds of scientific research. Dynamic models are the foundation of research on sounding rockets. However, no dynamic models have included all the working processes of a sounding rocket. A high-precision dynamic model of a sounding rocket is proposed in this article; the model includes motion on the launch rail, the free flight phase, parachute deployment, the inflation process, and steady descent. Through the model, the entirety of the dynamic process can be understood in detail to help improve performance. A combination wind compensation method was investigated to rapidly and accurately obtain launch parameters; the method was derived from a wind weighting and pattern search method. Based on the simulation results, the proposed approaches are proven to be effective.
