Document Type and Number:
WIPO Patent Application WO/2019/061083
Kind Code:
A1
Abstract:
A method of determining airspeed of a movable object (100) includes a calibration process to determine a relationship between forces exerted on the movable object (100) and airspeed of the movable object (100). Forces exerted on the movable object(100) while the movable object(100) is moving are determined, and the airspeed of the movable object(100) is determined based on the determined forces and the relationship.
