Flying-around orbit design method for continuous visible light detection of GEO space target

Abstract

The present invention discloses a flying-around orbit design method for continuous visible light detection of a GEO space target. The method comprises an approaching stage of a detection spacecraft toa target spacecraft and a flying-around stage of the detection spacecraft to the target spacecraft. Firstly, a flying-around orbit is designed, and for the designed flying-around orbit, the orbital maneuvering scheme in the approaching stage is designed by taking the most fuel-saving effect as an optimization goal; the key to the design of the flying-around orbit is to determine an initial phasewindow of the detection spacecraft flying around relative to the target spacecraft, an initial phase that meets the requirements is selected, and the flying-around orbit is designed according to the CW equation; and then an approaching-stage orbit is designed, and the key to the design of the approaching-stage orbit is to determine the two moments of the Lambert orbital maneuver. According to themethod provided by the present invention, the periodic factors of the GEO space target flying around are combined, the solar lighting conditions are fully considered, and the designed flying-around orbit can keep the detection spacecraft always facing the sun to perform visible light detection on the target spacecraft and can effectively meet situational awareness and on-orbit service missions ofthe GEO space target.

Description

technical field [0001] The invention relates to a orbit design method for continuous visible light detection of a GEO space target, and belongs to the technical field of spacecraft orbit design. Background technique [0002] Geostationary Orbit (GEO) deploys a large number of high-value space resources due to the particularity of its orbit. On May 2, 2019, the Space Debris Office of the European Space Agency stated in the "European Space Agency Annual Space Environment Report" that as of 2019 On January 1, there were a total of 884 spatial objects in the GEO region. GEO space targets are nearly 36,000 kilometers away from the ground, which brings great challenges to ground-based high-definition observations. Deploying optical imaging remote sensing satellites in the GEO area to observe GEO space targets has strong anti-interference capabilities, and can obtain clearer images and better judge GEO The working status of the space target, in addition to designing the orbit arou...

[0004] However, the fly in the ointment of previous studies is that they did not analyze the time constraints and did not consider the orientation of the sun in the process of analyzing the orbiting flight. Therefore, if the window for entering the orbiting flight is not selected properly, the detection spacecraft may not meet the requirements for the visible light of the GEO space target.
