Embodiment Construction

[0038] Such as Figure 1-17 As shown, this embodiment elaborates in detail on the control method for distributing in different plane orbits of the space-based dispenser:

[0039] A space-based dispenser dissemination control method in different plane orbits, the method is realized based on the target satellite and the dispensing satellite operating in a similar different plane orbit with the same orbital radius and a certain orbital inclination angle difference, the method The implementation process is:

[0040] Step 1: Detect the target, and obtain its initial relative velocity v' relative to the distributing satellite at time 0 0_tar and the initial relative position r' 0_tar ;

[0041] Step 2. Set t adjust The time dispenser finishes launching the interference material;

[0042] Step 3, solve t adjust The relative velocity v of the target star relative to the distributing satellite at all times 0_tar , relative position r 0_tar ;

[0043] r 0_tar (t adjust ) = Φ ...

Abstract

The invention provides a space-based dispenser different-plane orbit dispersion control method, and relates to the technical field of satellite control. The method aims to accurately control a satellite which is launched to be close to different-plane orbits of a target satellite and provided with a dispenser to spray interference cloud clusters so as to interfere the target satellite so that the target satellite can loss corresponding functions. The tadjust moment when the dispenser completes jetting of interference materials; v0_tar and r0_tar of the target satellite relative to a dispersion satellite at the tadjust moment are solved; cosine values of triaxial included angles of theta x, theta y and theta z of an orbit system of a dispenser spray head and the dispersion satellite and expected hit time thit are calculated by utilizing r0_tar and v0_tar to solve an equation set at the same time; if thit has a proper positive real number solution, the relative state of the two satellites is in a jetting window, and the next step can continue to be conducted; otherwise, the two satellites wait for entering the jetting window; the theta x, theta y and theta z are figured out within time less than tadjust - tjet, and the dispenser spray head is controlled to point to the expected jetting direction; the interference cloud clusters begin to be jetted at the tadjust - tjet moment and are made to separated from the dispenser thoroughly at the tadjust moment. The method is applied to the anti-satellite control process.

Description

technical field [0001] The invention relates to a dispensing control method of a space-based dispenser, and relates to the technical field of satellite control. Background technique [0002] Satellites have incomparable advantages in supporting global precision strikes, global mobile operations, and seizing information initiative. Without the support of military satellites, any modern weapon system cannot play its due role. At the same time, the huge role of military satellites has also promoted the development of anti-satellite weapons. There are various types of anti-satellite weapons, among which the rendezvous attack is developed on the basis of space rendezvous and docking and missile guidance technology. [0003] Anti-satellite weapons generally perform several orbital maneuvers under the remote control of the ground station, transfer from the latent orbit to a certain range from the target star, and then approach the target star autonomously under the action of the o...
