Building ballistic trajectory of ballistic missile with multiple-stage boosters and calculating ballistic missile’s position are pre-requisite for constructing ballistic missile early warning simulation system. The forces acting on the ballistic missile has been analyzed and a dynamics model describing the motion of ballistic missile which contains multiple-stage boosters has been addressed. The effect of three different Earth models on ballistic missile’s trajectory has been analyzed and the kinetic model of ballistic missile which contains multiple-stage boosters has been educed. A trajectory of ballistic missile which contains two-stage boosters has been simulated, the trajectory of jettisons of two-stage boosters also has been simulated. The effort of models and simulation has important significance for the research of tracking ballistic missile with multiple-stage boosters.
