Problems solved by technology

[0003] At present, the reconnaissance and monitoring of hotspot areas by optical imaging remote sensing satellites is still passive and completes the prescribed imaging tasks according to the pre-arranged mission instructions on the ground. The risk is high; the visible light load is the whole star load, and the direct use of the star's maneuverability to capture the moving target in the air and complete the capture, tracking and reconnaissance greatly wastes the whole star resources

Embodiment

[0220] A method for synergistic control of pan-tilt pointing and star attitude for tracking a moving target in the air, the motion law of the moving target in the air is unknown;

[0221] Firstly, the relevant parameter definitions are given: the attitude of the satellite in the orbital coordinate system is [φ θ ψ}] T , 3-1-2 The sequence is to first rotate ψ around the Z axis, then rotate φ around the X axis, and then rotate θ around the Y axis, and the rotation matrix is ​​expressed as C Bo ; The installation matrix of the pan / tilt in the body coordinate system is expressed as C PB ;

[0222] The rotation angle of the gimbal around the X axis is defined as α, the rotation angle of the gimbal around the Y axis is defined as β, and the rotation sequence of the gimbal is defined as rotating around the X axis first, and then rotating around the Y axis;

[0223] The camera installation matrix installed on the gimbal is a unit matrix, and the pixel size of the gimbal camera is d...

Abstract

The invention relates to a pan-tilt pointing and satellite attitude cooperative control method for air moving target tracking, belonging to the technical field of satellite control. The pan-tilt pointing and satellite attitude cooperative control method for air moving target tracking integrates and applies the pan-platform and the pan-platform camera technology in the satellite system for the first time, so that the whole satellite has the tractive situation perception ability to the moving target and the matching on-board real-time response ability to the emergency task, and fully expands thefunction of developing and utilizing the high-mobility remote sensing satellite and the whole satellite resources.

Description

technical field [0001] The invention relates to a cloud platform pointing and star attitude cooperative control method for tracking moving targets in the air, belongs to the field of satellite control technology, and is suitable for autonomous task planning tasks of capturing and tracking unknown moving targets at low altitudes for imaging loads operating in low orbits . Background technique [0002] Aircraft play an important role in the military field and civilian commercial field, and have high identification and tracking value. They are a typical type of air moving targets. The identification and tracking of military hotspots, including military airports and aircraft carrier combat formations, can keep abreast of the strategic dynamics of the target area, and obtain timely and effective campaign and tactical information as an important strategic support resource. In the civil and commercial field, the dynamic identification of civil aviation aircraft in the air can assi...
