1. A method comprising:
- collecting motion data comprising yaw data, pitch data, and/or roll data from a plurality of motion sensor tags disposed on an object comprising at least two segments, wherein at least one motion sensor tag is disposed on each of the two segments;
transmitting the motion data via at least one radio frequency signal;
receiving the motion data via at least one antenna array disposed on the object, wherein receiving the motion data further provides direction of arrival data, amplitude data, and phase data from the radio frequency signal; and
processing a collected data set comprising the motion data, the direction of arrival data, the amplitude data, and the phase data, wherein said processing provides three-dimensional data comprising a position, an orientation, an acceleration, and/or a velocity of the object in a three-dimensional space.

Abstract
Methods and systems for determining the motion of an object by capturing motion data. The methods and systems may comprise the use of motion sensor tags adapted for disposal on an object, wherein motion data may be collected by said motion sensor tags and transmitted via radio frequency signal for processing of collected data comprising the motion data, direction of arrival data, amplitude data, and phase data. The same system may also be adapted to determine the position of a UAV or aircraft by intercepting radio frequency communications signals emanating from the object.
