Patent Images
1. A method comprising:
- modeling an acceleration of an unmanned aerial vehicle (UAV) based at least on a measured ground speed of the UAV;
determining an actual acceleration of the UAV with one or more sensors; and
estimating a speed of the wind as an integral of a difference between the modeled acceleration and the actual acceleration.

Abstract
The speed of the wind during operation of a UAV is estimated. In one example the speed of the wind is estimated by modeling an acceleration of an unmanned aerial vehicle (UAV) based on a measured ground speed of the UAV, determining an actual acceleration of the UAV with one or more sensors, and estimating the speed of the wind as an integral of a difference between the modeled acceleration and the actual acceleration.

16. An unmanned aerial vehicle (UAV) comprising:
-
a plurality of sensors mechanically connected to the UAV; and a processor configured to model an acceleration on the UAV based at least on a ground speed of the UAV measured based on data from at least one of the sensors, determine an actual acceleration of the UAV with at least one of the sensors, and estimate the speed of the wind as an integral of a difference between the modeled acceleration and the actual acceleration. - View Dependent Claims (17, 18, 19)
