New CellLocate feature of LEON GSM module supports indoor positioning and eliminates “no-fix” scenarios
u-blox adds a cellular positioning technology CellLocate to its LEON GSM/GPRS module family to provide positioning in poor GPS signal conditions, or even without a GPS system present. This revolutionary embedded technology complements u-blox GPS by adding a parallel and complementary technique for determining position.
“GLEON with CellLocate provides benefits in several use cases:
* Enhanced stolen vehicle tracking (SVT)
CellLocate enhances 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.
* Tracking of valuable goods or containers when inside buildings and tunnels
Based on the extension of u-blox’ AssistNow Online GPS assistance service, u-blox’ proprietary CellLocate architecture leverages mobile network parameters to support indoor positioning based on GSM base station attributes. This is useful when tracking valuable assets and containers when they are inside warehouses, airports, or tunnels where GPS satellites are blocked, eliminating “no-fix” scenarios.
* Personal tracking
The technology can be used as a back-up positioning system for tracking of people who spend significant time within building where GPS does not work: GPS is used when outdoors, CellLocate when inside.
The CellLocate of LEON provides a single API regardless of the available positioning technology. LEON selects the optimal positioning solution based on user-defined configuration settings.
The above scenarios use cell and/or GPS positioning techniques to deliver better results than either technology could accomplish alone. The technology eliminates “no-fix” scenarios by providing at least an approximate fix wherever cell phone coverage is available, while overcoming GPS jamming scenarios to improve antitheft system performance.
u-blox‘ CellLocate cellular positioning technology is a feature implemented in u-blox LEON 2.5G wireless modem families.
