1. A method of operating an unmanned aerial vehicle (UAV), the method comprising:
- receiving, from a three-axis magnetometer, a single measurement representative of an attitude of the UAV, wherein the single measurement is of only one axis of the three-axis magnetometer;
comparing the single measurement to an allowable range of attitudes;
determining that the single measurement is not within the allowable range of attitudes; and
performing at least one corrective action on the UAV based only on the determination that the single measurement of the only one axis of the three-axis magnetometer is not within the allowable range of attitudes.

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.

9. An unmanned aerial vehicle (UAV) comprising:
-
an engine; a three-axis magnetometer configured to measure an attitude of the UAV; and a processor connected to the magnetometer and configured to; receive, from the magnetometer, a single measurement representative of the attitude of the UAV, wherein the single measurement is of only one axis of the three-axis magnetometer; compare the single measurement to an allowable range of attitudes; determine that the single measurement is not within the allowable range of attitudes; and perform at least one corrective action on the UAV based only on the determination that the single measurement of the only one axis of the three-axis magnetometer is not within the allowable range of attitudes. - View Dependent Claims (10, 11, 12, 13, 14)
