technical field [0001] The invention belongs to the field of on-orbit management of space vehicles, and in particular relates to a satellite co-location analysis modeling method and system based on hybrid orbit control technology. Background technique [0002] A certain satellite (hereinafter denoted by A star) is a technical test and communication satellite based on Dongfanghong-3 B platform, with two hybrid powers of chemical propulsion and electric propulsion onboard, and it has been in the environment of three-star co-location mission for a long time. The Dongfanghong-3 B platform is a newly developed platform. It is the first time in China to use hybrid power for position control. The traditional chemical propulsion orbit control strategy is not suitable for electric propulsion orbit control. Electric propulsion has high specific impulse but small thrust, and frequent maneuvers lead to complex orbit control strategy design scenarios, many constraints, huge amount of ana...
