Abstract

The invention discloses a coordinated relative positioning method and system for an aircraft cluster. According to the relative distance between the undetermined coordinates of each aircraft in the aircraft cluster and the aircraft, the theoretical pitch angle and theoretical azimuth of the aircraft relative to the target An observation equation system is constructed from the geometric relationship of the angles, and the measured values ​​of the pitch angle and the azimuth angle of each aircraft in the aircraft cluster relative to the target are obtained according to the obtained angular sensors on each of the aircraft, and the obtained values ​​of each aircraft and the azimuth angle are obtained. The relative distance measurements between other aircrafts are optimized and solved by using the observation equations to obtain the coordinate positions of each aircraft. Compared with the existing relative positioning method, the method proposed by the present invention simplifies the requirements for the configuration of the aircraft measuring equipment, and is more convenient to implement. Moreover, in the present invention, relative positioning is achieved by using mutual ranging between aircrafts, which can obtain higher relative positioning accuracy compared with the prior art.

Description

technical field [0001] The invention relates to the field of positioning and navigation of aircraft, in particular to a method and system for cooperative relative positioning of aircraft clusters. Background technique [0002] No matter in the military or civilian fields, the ability of a single aircraft to perform tasks is always limited, and a cluster aircraft composed of multiple aircraft cooperates with each other has advantages that a single aircraft cannot match, such as functional distribution, high cost efficiency, large-scale situational awareness, high task completion probability, etc. [0003] The high-precision motion coordination of swarm aircraft, such as precise formation flight, is inseparable from the high-precision relative position information between aircraft, and the coordinated guided attack of swarm aircraft on non-cooperative targets not only requires precise relative positioning between swarm aircraft, but also requires cooperation with non-cooperati...
