Abstract
Embodiments of the present disclosure related to methods and systems of determining the position of a device in indoor space. A map importing module takes a floor map of an indoor space and processes it for further use. A calibration module creates a fingerprint map of the indoor space described by the floor map. A positioning module uses the calibration data embodied in a fingerprint map as well as device signal and sensor readings in order to estimate a trajectory for the device, then position the device within the indoor space described by the floor map using a probability density function.
