Abstract
A location of a mobile terminal in a given area may be determined by including the mobile terminal in a satellite-based positioning system and in a cellular communications system. The approximate coordinates of the mobile terminal may be determined based on both satellite signals received from the satellite-based system and information related to the cellular communication system, where the coordinates include an altitude coordinate. An estimate of the altitude coordinate may be derived from the information related to the cellular communication system. The approximate coordinates may be determined using the estimate of the altitude coordinate and information provided by the satellite-based system by providing an approximate bi-dimensional positioning of the terminal and exploiting the bi-dimensional positioning and the estimate of the altitude coordinate.
