By using the nonlinear programming theory, a optimal impulse satellite evasive trajectory planning model considering earthoblateness perturbation had been established.
The first part is to analyze the two error sources of the earth horizon sensor: one is earthoblateness and the other is non-uniformly distributed atmospheric infrared radiation.
分析了引起地平仪测量误差的主要误差源—地球扁率和大气红外辐射不均匀性。

When solving required velocity, it real-timely thinks about influence of oblateness of the earth and gives the process of solving required velocity by midcourse trajectory method.
