Near-earth orbit spacecraft all-phase rendezvous and docking task planning method and system

The invention relates to the technical field of spaceflight measurement and control, and particularly discloses a near-earth orbit spacecraft all-phase rendezvous and docking task planning method and system, and the method comprises the steps: calculating an initial orbit condition between a target spacecraft on a near-earth orbit corresponding to a to-be-planned all-phase rendezvous and docking task and a tracking spacecraft, the docking constraint conditions of the target spacecraft and the tracking spacecraft under the target task requirement are obtained; based on the initial orbit condition and the docking constraint conditions of the target spacecraft and the tracking spacecraft under the target task requirement, generating measurement and control resources and flight control events required by the to-be-planned all-phase rendezvous and docking task; and according to the relative constraint relationship, performing time sequence planning on the flight control event and the docking instruction module inc
