Abstract
A method performed by a system (120) for determining a position of a device (140) connected to a communication network (100) is disclosed. The method comprises obtaining a geographical area for the device based on a first position-estimation service, obtaining information on luminosity on the device over a time period, and determining a second position estimation for the device (140) based on the geographical area and on the information on luminosity, by comparing the information on luminosity over the time period to a 3D model of the geographical area, the 3D model comprising models of 3D objects of the geographical area and a model of sunlight shining onto the models of the 3D objects over the time period. Disclosed is further a corresponding system and a position-determining method performed by a communication device.
