CSR Creates Enhanced Global Positioning System Technology

CSR announced it has successfully integrated GPS with cellular measurements to create eGPS® (enhanced Global Positioning System) technology capable of providing accurate position information on demand in all environments. CSR will be demonstrating the benefits of eGPS technology at Mobile World Congress (MWC 08) in Barcelona. CSR’s location technologies are now proven to provide significant power and performance improvements necessary for embedding into a mobile handset. CSR’s first single-chip GPS with embedded Bluetooth and FM radio technologies is back from the fab and proven working. CSR’s eGPS demonstrations take place at Mobile World Congress Hall 1, stand 1E51 from 11 – 14 February 2008.

CSR’s CEO, Joep van Beurden commented, “Along with last month’s announcement of the intention to form the EGPS Forum with Motorola, our working silicon and demonstrations at Mobile World Congress are all significant steps on CSR’s roadmap towards adding high performance, yet power-efficient eGPS to cellular phones at an additional cost of less than $1.” van Beurden continued, “Our patented eGPS technologies are ready to change the market for location technologies in mobile handsets.”

CSR’s GPS demonstrations at MWC 08 will show its technologies providing real-time GPS navigation embedded in a mobile handset as well as improving the responsiveness and availability of accurate position information compared with assisted GPS (A-GPS) in a live cellular network.

CSR’s patented eGPS techniques augment traditional GPS or A-GPS with cellular network measurements to provide a much improved user experience. Universal availability of location information, increased responsiveness and reduced power consumption make eGPS far more appropriate for use in mobile handsets when compared with current GPS technologies. eGPS works globally, providing far more accurate position information than conventional cellular-based technologies and allowing carriers to support the fine time aiding critical to GPS performance in difficult environments without needing expensive overhauls of unsynchronised GSM or W-CDMA network infrastructure.

In January, CSR and Motorola announced their intention to create the EGPS Forum.

CSR’s eGPS demonstrations show how its technology can be easily embedded into a standard slimline handset and minimises power usage as well as avoiding conflicts with other handset technologies. Using off-the-shelf mapping software, CSR’s handset demo shows highly accurate turn-by-turn navigation driven by signal processing software running entirely upon the embedded host applications processor. 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. A typical eGPS push-to-fix will be available in less than 4 seconds, accurate to within 10 metres and require the equivalent power of less than 1 second of handset talk time.

CSR has a long history of success in embedding radio technologies in mobile handsets for customers such as Nokia, Motorola and Samsung. In January 2007 CSR announced its acquisition of GPS specialists NordNav Technologies AB and Cambridge Positioning Systems. By combining its expertise with that of its acquisitions CSR has been developing eGPS product offerings that support satellite navigation and other location-based services.
