No-manned plane fixed radius convolved navigation method

Abstract

The invention discloses an unmanned aircraft fixed radius circling navigation method. The position and height of the aircraft and the ground speed information are gained according to the given circling radius, anticipant circling type and a sensor, the navigation parameters such as lateral deviation and lateral deviation velocity, etc., of the anticipant track of the aircraft continuously calculated in real time, together with the aircraft gesture motion information gained by a gesture motion sensor, are input into a lateral control circuit to obtain a rudder deflection instruction, and the aircraft is finally guided to fly along the anticipant flight course. The navigation method provided by the invention can realize guiding the aircraft to carry out the cycling flying with fixed radius and avoids the frequent shifting of straight flying and turning motion in the broken-line flying process; the aircraft body bears small overload, and can fly according to the anticipant track under the situation of wind interference.

Description

technical field [0001] The invention belongs to the field of unmanned aerial vehicle navigation, and specifically refers to an unmanned aerial vehicle fixed-radius hovering pilot technology. Background technique [0002] Because it is rarely restricted by weather conditions, it can sneak into the sky over enemy targets for day and night reconnaissance, and accurately transmit real-time target images and information to the combat command center, so that battlefield commanders can grasp the battlefield situation in time and formulate combat plans. It has gradually demonstrated its great power in local wars. [0003] The basic task of UAV navigation is to accurately determine the spatial position of the aircraft and enable it to fly along the desired trajectory. The current area navigation method can allow the aircraft to fly any desired flight path within the coverage area of ​​the reference station of the station-based navigation equipment or within the limited range of the ...

AI Technical Summary

Problems solved by technology

Use the fixed roll angle deflection to make the aircraft circle around a certain circle center, but if it is disturbed by the crosswind during the circle, because the aircraft does not control its own position, the aircraft will not fly along the desired trajectory, so it is difficult to obtain accurate The reconnaissance results of
