Abstract
A method and apparatus for using inertial navigation for obtaining calibration data for an indoor positioning system are disclosed. In one embodiment, the method comprises tracking motion of a device between known locations within a structure using inertial navigation, collecting a plurality of Wi-Fi signatures with the device while tracking the motion of the device between the known locations, and matching each of the plurality of Wi-Fi signatures to a point between the known locations, where the matched Wi-Fi signatures are for use in comparing to Wi-Fi signatures being received by the indoor positioning system to identify an indoor location of a device within the structure.
