CSR’s eGPS claims it is better than A-GPS

NaviGadget: UK’s CSR just announced that have integrated GPS with cellular measurements to create eGPS - enhanced Global Positioning System - technology capable of providing position information on demand in all environments. We’re not exactly quite sure how eGPS works just yet but the press release claims it has better TTFF than A-GPS and less power consuming.

“A comparative demo against conventional A-GPS systems shows greatly improved time to first fix (TTFF) in difficult environments and a reliable fallback position based on cellular measurements when A-GPS fails. CSR’s Bluetooth silicon with embedded support for eGPS allows satellite measurements to be maintained when the host processor is powered down, providing position information on demand while minimising power and resource loads.”
