Abstract
A method is provided for determining a location of a mobile device in a wireless network. The method includes receiving global navigation satellite system (GNSS) measurements from the mobile device, and receiving terrestrial measurements from corresponding transceivers in the wireless network, each terrestrial measurement indicating a distance between the corresponding transceivers and the mobile device. The method further includes selecting at least one terrestrial measurement having an uncertainty value within a predetermined accuracy threshold. The location of the mobile device is determined as a function of the GNSS measurements and the selected terrestrial measurement.
