Research on Maintenance Control Method of High-Precision Regressive Orbit Based on Virtual Formation Configuration

Aiming at the problem of high-precision regressive orbit maintenance control of satellites in low-earth orbit, the concept of virtual double satellite formation configuration is introduced, and the divergence mechanism of virtual double satellite formation configuration and pipeline space deviation under the influence of low-earth space environment is analyzed, and the constraint relationship between which is obtained. A high-precision regressive orbit maintenance control strategy is designed by combining fixed period and threshold trigger. The numerical simulation results show that: The application of this control strategy, especially the semi-major axis overshoot control, can reduce the number of satellite orbit corrections by using natural perturbation as much as possible, avoid frequent satellite correction control and reduce the consumption of spaceborne propellant. This research result has guiding significance for satellite orbit maintenance control with high-precision regressive orbit requirements.
