The main function of orbitcalculation is to simulate the flight procedure of spacecraft, before that, the dynamics model of orbit must be established.
轨道计算主要用来模拟飞行器的飞行过程,前提是建立动力学模型。

Chapter 3 analyzes numerically the effects for orbitcalculation caused by orbital perturbation, parameter error and so on. A precise mathematical model of orbitcalculation is given.
