Abstract
Systems and methods are disclosed for determining a geographic position of a mobile communications terminal operable in a wireless communications network. According to one embodiment, a first estimated position of the mobile communications terminal may be calculated based on pseudo-range measurements related to a plurality of signals received from transmitters of a global navigation satellite system. Moreover, a second estimated position of the mobile communications terminal may be calculated based on information provided by the wireless communications network. The first estimated position may be analyzed to derive an indication of whether at least one of the pseudo-range measurements is affected by errors. If at least one of the pseudo-range measurements is affected by errors at least one third estimated position may be calculated based on a sub-set of pseudo-range measurements and evaluated against the first estimated position.
