Hybrid positioning systems are systems for finding the location of a mobile device using several different positioning technologies. Usually GPS is one major component of such systems, combined with cell tower signals, wireless internet signals, Bluetooth sensors or other local Positioning Systems. These systems are specifically designed to overcome the limitations of GPS, which is very exact in open areas, but works poorly indoors or between tall buildings.

  • Hybrid positioning systems are systems for finding the location of a mobile device using several different positioning technologies. Usually GPS is one major component of such systems, combined with cell tower signals, wireless internet signals, Bluetooth sensors or other local Positioning Systems. These systems are specifically designed to overcome the limitations of GPS, which is very exact in open areas, but works poorly indoors or between tall buildings. By comparison, cell tower signals are not hindered by buildings or bad weather, but usually provide less precise positioning. Wi-Fi signals may give very exact positioning, but only in urban areas with high Wi-Fi density - and depend on a comprehensive database of Wi-Fi access points. Hybrid positioning systems are increasingly being explored for certain civilian and commercial location-based services and location-based media, which need to work well in urban areas in order to be commercially and practically viable. Different hybrid positioning systems are currently being developed and used in services from Navizon, Xtify, PlaceEngine, SkyHook, Google Maps for Mobile for application in smartphones including Apple iPhone. The maturity of these systems approaches requires proofing in operational use.
