Title:
SYSTEM AND METHOD FOR ESTIMATING POSITION OF UAV
Document Type and Number:
Japanese Patent JP2019007964
Kind Code:
A
Abstract:
To improve tracking accuracy and tracking robustness of aviation vehicles under various conditions, for various applications requiring high accuracy and precision.SOLUTION: A system, a method, and a device are provided which determines a relative position between movable objects and improves positioning accuracy. A method for positioning at least one mobile tracking device relative to at least one target object may be provided. The method comprises the steps of: obtaining an estimated location of the target object; and determining a relative position between the target object and the mobile tracking device on the basis of the estimated location of the target object, an estimated location of the mobile tracking device, and a correction amount.SELECTED DRAWING: Figure 1
