Research of Circular-Like Satellite Formation Flying at Critical Inclination

In this paper, the passive and periodic circular-like formations design at critical inclination under J₂ perturbation is proved to be correct. The software STK is used to make highly precision simulation under J₂ perturbation, full perturbation and so on. The effect of other perturbations on the passive and periodic circular-like satellite formations can be obtained according to simulation. The initial value of circular-like formations including J₂ is more stable than not including it. However, the initial value not including J₂ perturbation is the same as including it when the true anomaly is the special value.
