Performing Corrective Action on Unmanned Aerial Vehicle Using One Axis of Three-Axis Magnetometer
First Claim
Patent Images
1. A method of operating an unmanned aerial vehicle (UAV) comprising:
- receiving from a three-axis magnetometer a measurement representative of an attitude of the UAV, wherein the measurement is of only one axis of the three-axis magnetometer, thereby reducing the amount of time required to determine the attitude of the UAV;
comparing the measurement to an allowable range of attitudes;
determining that the measurement is not within the allowable range of attitudes; and
performing at least one corrective action on the UAV.

Abstract
Methods and systems are provided for using a measurement of only one axis of a three-axis magnetometer to perform at least one corrective action on an unmanned aerial vehicle (“UAV”). An exemplary embodiment comprises (i) receiving from a three-axis magnetometer a measurement representative of an attitude of a UAV, wherein the measurement is of only one axis of the magnetometer, (ii) comparing the measurement to an allowable range of attitudes, (iii) determining that the measurement is not within the allowable range of attitudes, and (iv) performing at least one corrective action on the UAV.
