Same orbit plane satellite observation orbit design method under nature accompanying condition

Abstract

The invention discloses a same orbit plane satellite observation orbit design method under a nature accompanying condition; the method comprises the following steps: designing an observation satellite initial orbit satisfying the nature accompanying condition with a target satellite; setting a visual direction, relative to the observation satellite, of the target satellite as the observation direction, and keeping space inertia orientation of the observation satellite in a flying process; selecting a visual angle of an observation camera; determining an observation direction and target satellite connecting line angle long-time cycle radiate model; adjusting the observation satellite gesture according to the long-time cycle radiate model. The satellite observation orbit design method can reduce the observation satellite space flying orbit gesture orbit coupling maneuvering requirement; a control system and an execution mechanism are simple, and cost is low.

Description

technical field [0001] The invention relates to the field of space observation, in particular to a satellite observation orbit design method under the condition of natural accompanying flight in the same orbit plane. Background technique [0002] Space observation and on-orbit service technology are currently research hotspots in the field of aerospace technology. Satellite orbiting observation technology is an important space control technology, which plays an important role in space activities such as on-orbit inspection and identification of space targets. Prerequisites for activities such as services. At present, one is natural fly-by observation, which has few chances and low target resolution. Most of the fly-by observation satellites carry precise navigation equipment and control actuators, which consume a lot of propellant, and the control system and actuators are complicated and costly. Contents of the invention [0003] In view of the problems existing in the ab...
