Abstract: The maintenance control method for strictly-regressive orbit of near earth satellites is investigated. Firstly, the satellites' formation flying theory is used in this control, and the concept of "virtual formation flying satellites" is proposed. Then, applying this concept, the satellite's tube radius error relative to the reference trajectory is simulated and analyzed. Based on the relative movement of formation flying satellites, the accumulated departure of the satellite is deduced using formation flying parameters and relative orbit elements. Furthermore, the tube maintenance strategy is designed, featuring the orbit elements overshooting, offsetting and threshold trigger. Finally, numerical simulation results show that the satellite's orbit could be controlled in the orbit tube with this strategy and the short-term periodic perturbation can be reduced effectively. The study can be used in the maintenance control of satellite's orbit with strictly-regressive orbit demands.

Key words: strictly-regressive orbit, maintenance control, offsetting control, virtual formation flying satellites, tube radius error
