发明名称 Method and apparatus of obtaining improved location accuracy using magnetic field mapping
摘要 Method and apparatus of increasing location accuracy of an inertial navigational device is described. The inertial navigation device generates real-time data and transmits the real-time data to a second device so that the second device may obtain a location of the inertial navigational device. The inertial navigational device receives an update message from the second device, wherein the update message is created at the second device based on a comparison of the real-time data generated by the inertial navigational device against a magnetic field database and adjusts the depicted location of the inertial navigational device based on the update message in order to increase the location accuracy of the inertial navigational device.
