Abstract
The present disclosure relates to systems and methods for determining the location of a WLAN and cellular position system enabled device using a WLAN position estimate to select the best cellular positioning system location. The method can include estimating a position of the WLAN and cellular enabled device using a WLAN positioning system and an expected error estimate for the WLAN based position estimate, determining a set of possible cellular based position estimates for the WLAN and cellular enabled device using cellular measurements obtained from at least one cell tower, determining an uncertainty area around the WLAN location estimate based on the expected error of the WLAN location estimate, and determining the device location by selecting cellular based location estimates located within the uncertainty area.
