摘要： Systems and techniques for sensor-derived object flight performance tracking are described herein. A set of magnetometer readings may be obtained from a magnetometer included with an object. A local rotation axis of the object may be determined at a time using the set of magnetometer readings. The local rotation axis may describe rotation of the object around a local magnetic target. A global rotation axis may be calculated based on an initial orientation of the object. The global rotation axis may describe a fixed rotation axis of the object during flight in a global coordinate frame, wherein an angle between the global rotation axis and magnetic north remains constant during the flight. An orientation of the object may be determined for the time using the global rotation axis and the local rotation axis of the object at the time.

摘要： The present disclosure describes a number of embodiments related to devices, systems, and methods locating a an object using ultra-wide band (UWB) radio transceivers embedded in carpet or other flexible material that may be rolled up and moved to various locations. Once in a location, the carpet may be unrolled and the multiple embedded radio transceivers may receive a signal from a tag attached to the object sending UWB radio signals. Based on the signals received by the UWB radio transceivers, various processes including time-difference on arrival, time-of-flight, and phase shift may be used to determine the location or the movement of the object.
