Swiss company releases "indoor" GPS system

U-blox a Swiss provider of GPS receivers announced an apparently very sensitive GPS device. The LEA-4H, the company claims, is able to receive "the weakest signals" - even in places with obstructed views. In fact, the device is sensitive enough to calculate geographical positions within in buildings.
Acquisition and reacquisition sensitivity of the LEA-4H is rated at -148 dBm, cold start sensitivity at -142 dBm and tracking sensitivity at -158 dBm, U-blox said. The device is also Assisted-GPS capable.
