u-blox added a cellular positioning architecture called CellLocate to its LEON GSM/GPRS module family to provide positioning in poor GPS signal conditions, or even without a GPS system present. This technology complements u-blox GPS by adding a parallel and complementary technique for determining position.
CellLocate can enhance stolen vehicle tracking (SVT) by enabling approximate vehicle positioning in relation to GSM base station locations, a feature that is useful especially in the presence of GPS jammers, or if a vehicle is hidden inside a metallic trailer. This is also useful when tracking valuable assets and containers when they are inside warehouses, airports or tunnels where GPS satellites are blocked, eliminating ‘no-fix’ scenarios. The technology can be used as a backup positioning system for tracking of people who spend significant time within buildings where GPS does not work.
The CellLocate feature of LEON provides a single API regardless of the available positioning technology. LEON selects the optimal positioning solution based on user-defined configuration settings.
