Abstract

The invention discloses a regional hovering orbit control method based on constant continuous thrust, and the method comprises the steps: giving a theoretical track of a regional hovering orbit according to a raindrop shape hovering configuration design method; then selecting two points from the two sides of the raindrop sharp point to serve as a starting point and an ending point for constant continuous thrust control over the task spacecraft orbit, and calculating the total control duration and the theoretical value of the absolute orbit element variation of the task spacecraft after control; and finally, by constructing a constant continuous thrust orbit control equation, calculating a regional hovering orbit control strategy based on constant continuous thrust, and achieving long-termhovering of the mission spacecraft relative to the target spacecraft in a specified region. Aiming at the requirement of an on-orbit service task for a hovering technology, the invention provides a constant continuous thrust control strategy for realizing spacecraft regional hovering, and solves the problem that the existing regional hovering orbit pulse control method is not applicable under thecondition that a spacecraft is equipped with a continuous thrust engine.

Description

technical field [0001] The present invention relates to the technical field of spacecraft hovering, and in particular to an orbit control method applied to spacecraft regional hovering tasks, and further refers to an orbit control method for realizing spacecraft regional hovering by using constant continuous thrust. Background technique [0002] Spacecraft hovering technology is a research hotspot in the aerospace field. Spacecraft hovering means that the relative position of the task spacecraft (Chsaing Satellite, CS) to the target spacecraft (Reference Satellite, RS) remains unchanged or changes within a small range under the action of control force for a period of time. . During the mission spacecraft performing on-orbit service tasks, it often involves observation, monitoring, inspection or diagnosis of the target spacecraft, and the realization of these functions requires the use of the key technology of hovering. With the increasing number of on-orbit service mission...
