Title:
METHOD AND SYSTEM FOR INDOOR POSITIONING OF A MOBILE TERMINAL
Document Type and Number:
WIPO Patent Application WO/2016/068742
Kind Code:
A8
Abstract:
The present method and system can be used for indoor positioning where navigation satellite signals are unavailable. According to the method, features identifying the location of a mobile terminal in a defined position are determined on the basis of data received from at least one inertial and non-inertial sensor during the movement of at least one mobile terminal; the trajectory of movement of the above-mentioned mobile terminal in a local coordinate system associated with the above-mentioned position and also data from non-inertial sensors are defined and stored; statistically averaged conversion parameters of the local coordinate systems of the mobile terminal in positions defined during the movement of the terminal are generated; at least one map of the distribution of outputs from the non-inertial sensors is generated on the basis of the data obtained in the previous step; the position of the above-mentioned mobile terminal is defined on the basis of the data obtained in the previous step. The system consists of a plurality of mobile terminal sensors, a computer, a probability calculation module, a feature determination module, a set of data banks and a coordinate converter.
