Title:
AUTONOMOUS NAVIGATION SYSTEM AND METHOD BASED ON MILLIMETER-WAVE INTEGRATED SENSING AND COMMUNICATION UNMANNED DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/082475
Kind Code:
A1
Abstract:
Disclosed in the present invention are an autonomous navigation system and method based on a millimeter-wave integrated sensing and communication unmanned device. The autonomous navigation system comprises at least one intelligent unmanned system and at least one mobile communication base station, wherein the mobile communication base station sends signals to all users, and the signals include, but are not limited to millimeter wave signals; the intelligent unmanned system is provided in an unmanned device, and at least comprises an inertial navigation positioning system; and the intelligent unmanned system receives a millimeter wave signal from the mobile communication base station in real time, performs decoding to obtain identity information and location information of the base station in a frame header of the signal, and also estimates a relative location between the intelligent unmanned system and the base station according to the angle of emergence, angle of arrival, and time delay of arrival of the signal, corrects an accumulated error of the inertial navigation positioning system of the intelligent unmanned system itself according to the location, and determines the location of the intelligent unmanned system itself according to inertial navigation positioning and millimeter wave positioning, thereby realizing autonomous navigation. Millimeter wave signals in a free space are fully utilized to realize high-precision positioning and autonomous navigation without affecting a mobile communication system.
