Space attack and defense method based on solar eclipse effect

Abstract

The invention discloses a space attack and defense method based on the solar eclipse effect, which is used for performing shielding control on sunlight received by a target spacecraft, and comprises the following steps: determining spot hover orbit configurations of a task spacecraft and the target spacecraft; calculating an ideal relative position of the task spacecraft and the target spacecraft based on the fixed-point hover orbit configuration according to the operation orbit of the target spacecraft and the sun position, and controlling the task spacecraft to maneuver to the ideal relative position so as to form a solar eclipse effect on the target spacecraft; calculating and updating the ideal relative position of the task spacecraft and the target spacecraft at a preset time interval, and judging whether the actual relative position of the task spacecraft and the target spacecraft is within the range of a preset trajectory tracking error ball of the ideal relative position or not; and if not, controlling the task spacecraft to maneuver to the ideal relative position at the corresponding moment. According to the method, normal work of the target spacecraft can be interfered, irreversible damage to the target spacecraft cannot be caused, the concealment is high, and the collision risk does not exist.

Description

technical field [0001] The invention relates to the technical field of spacecraft control, in particular to a space attack and defense method based on solar eclipse effects. Background technique [0002] With the continuous development of aerospace technology, the number of spacecraft launched by various countries is increasing day by day. As space technology is an important symbol of a country in the aviation field, the battlefield of the great power game is gradually migrating to space. As a clean energy widely used in renewable energy, solar energy has been widely used in all walks of life, and it has also received more and more attention in the aerospace field. It is currently the main source of energy for spacecraft in orbit. The solar cells equipped on the spacecraft convert solar energy into electrical energy, provide electrical energy for the spacecraft's system work, and store the excess electrical energy in the battery for use as a supplementary power source during...

Problems solved by technology

However, the use of soft-kill methods requires close rendezvous or accompanying flight between the mission star and the target star, requires early maneuvering and approaching the target star, has high requirements on the control system, is easy to be discovered by the enemy, and has a risk of collision

If evasion measures are taken in advance, it is easy to cause mission failure
