Abstract:
A method for generating a model of an environment enabling positioning within the environment is disclosed. The method comprises: receiving distance-dependent measurements relating to a distance between a receiving unit position and a source position; receiving information relating to geographic positions, each defining a receiving unit position or a source position; forming a candidate model, which defines candidate source positions and candidate receiving unit positions; iteratively reducing a model error of said candidate model, wherein said model error comprises a weighted contribution from distance-dependent errors, which are based on a difference between a distance-dependent value between a candidate source position and a candidate receiving unit position and the corresponding distance-dependent measurement, and geographic position errors, which are based on a difference between a geographic position and a corresponding candidate position, and outputting, from said iterative reducing, determined locations for said plurality of sources to form said model of the environment.

Claim (Index 16):
An apparatus for determining a location of a device; said apparatus comprising:\n a storage unit configured to receive and store first power-based distance measurements, each measurement representing a distance from the device to a source as a measured power of a signal received by the device; and a processing unit configured to:\n access a model defining source locations and radio frequency propagation properties in an environment, said source locations and radio frequency propagation properties being determined based on a collection of second power-based distance measurements representing a distance from receiving units to source locations and at least one of: time-based distance measurements representing a distance from receiving units to source locations, sequential receiving unit positions, compass data, accelerometer data, gyrator data, sensor data indicating a relative floor in a building, and data correlating measurements at regular intervals, wherein said second power-based distance measurements are acquired prior to acquiring of the first power-based distance measurements and said receiving units are different from the device; and \n determine a location of the device based on the received power-based distance measurements and the source locations and the radio frequency propagation properties defined by the model.
