Method for compensating drift between inertial sensors wirelessly
The patent application (Publication Number: US20230392955A1) describes a method for compensating for drift between two inertial sensors by wirelessly transmitting data between them, computing orientation based on the transmitted data, and compensating for drift by estimating the drift between the sensors. The method involves correcting heading errors introduced by drift in the sensors' gyroscopes or accelerometers by applying a drift compensation factor. The drift estimate is computed based on the orientation of the sensors and can be used to improve the accuracy of measurements provided by the sensors.
Furthermore, the patent application details the use of antenna arrays to measure the angle of arrival of wireless data, allowing for more accurate orientation calculations. The method involves converting the direction of arrival into a global frame, projecting it onto a plane, and computing the drift estimate based on the projected directions. The process can be repeated multiple times to account for cumulative drift errors over time. Additionally, the application includes claims for an apparatus and a motion tracking system utilizing the described method to compensate for drift between inertial sensors, particularly useful for applications requiring precise motion tracking and orientation measurements.
