A low-cost, portable and simple alternative to GPS satellite location has been developed using mobile phone signals. Overview Mapping's Verilocation service is based on cell location and can pinpoint a registered phone with signals garnered from the UK's four major operators. It displays location data combined with Overmapping's own digital street-level maps on a website and is accurate to one hundred metres. Designed as a pay-as-you-go application, it is aimed at time/service critical industries considering GPS location and telemetry. However, anyone with a GSM phone could utilise the system, which ties location accurately to the road network, without unnecessary sub-two metre GPS precision.
Overview Mapping is licensed by Ordnance Survey and offers a range of mapping solutions to businesses, including internet portals.
