Low-orbit satellite orbit recovery method with low fuel consumption

The invention discloses a low-orbit satellite orbit recovery method with low fuel consumption, and belongs to the technical field of satellite orbit recovery. The invention aims to solve the problem that an existing orbit maneuvering method needs frequent orbit adjustment and is not beneficial to low-fuel-consumption in-orbit long-term operation of a satellite. Comprising the following steps: establishing an orbit kinetic equation considering earth oblateness perturbation; solving the initial number of transition orbits with low fuel consumption according to the current orbit and the target orbit of the satellite by using a semi-analytical method; calculating drifting time required by the satellite for drifting without fuel consumption on the transition orbit by utilizing the earth oblateness perturbation and the final number of the transition orbit at the transition end moment by combining the orbit kinetic equation; based on the Pontryagin maximum principle, thruster fuel optimal control rate sequences of t
