The possibility of using different techniques varies between devices and regions in space, according to the available hardware on the equipment and the infra-structure. This article presents the Uni- fied Cooperative Location System, which allows the use of every available technology to a mobile device, providing a higher availability of location services. Additionally, the system implements an information exchange mechanism, allowing devices to gather location information from nearby users, like GPS or Wi-Fi, which would otherwise be unavailable for some. The possibility of exchanging GSM information provides a viable solution for the gathering of multiple GSM signals by one device, thus significantly increasing location accuracy with this technology.
