eGPS: positioning technology that always works

Enhanced GPS (eGPS®) delivers a universal positioning capability that will not only work reliably indoors and in zero GPS signal conditions, but greatly speed time to fix in the poor GPS reception areas where most handsets are used.

It provides a superset of the assistance information provided by A-GPS to deliver reliable positioning - anywhere, anytime - without necessitating upgrades to existing GSM/WCDMA network infrastructure. 

eGPS exploits data available from the cellular network to speed GPS (or Galileo) fixes, and to provide complementary fast and reliable location sensing when GPS signals are weak or unavailable.

The technology meets the expectations of all parties: from carriers and users to regulatory authorities - creating a solid foundation for the growth of location based services and network equipment.

eGPS technology draws on intellectual property gained from CSR's acquisitions of Nordnav Technologies with its software based GPS system, and Cambridge Positioning Systems with its cellular location technology. CSR's wireless IC knowledge completed this portfolio, allowing the company to develop the first viable universal position sensing technology for deployment on handsets. CSR is also working with industry partners to standardise eGPS and develop enhancements.
