CSR, Rx Networks Partner on eGPS and Predicted GPS Positioning Technologies

(Product News, 16 Sep 2008)

CSR and Rx Networks Inc. have launched a GPS solution that combines their respective eGPS (enhanced Global Positioning System) and GPStream technologies. The joint solution optimally combines GPS fine time and frequency aiding with synthetic assistance, to yield mobile positioning performance that exceeds standard Assisted-GPS in unsynchronised GSM and W-CDMA networks, or in synchronised CDMA networks.

With the partnership, fine time, frequency aiding and ephemeris assistance are all generated locally in the device, and available at all times without the need for real time communication with a server. This eliminates up to 15s of network latency in mobile handset applications while remaining fully compliant with A-GPS industry standards such as SUPL 1.0.

Both CSR and Rx Networks operate carrier-grade service delivery infrastructures, through which Rx Networks' GPStream extended ephemeris technologies may be delivered. GPStream PGPS and SAGPS produce continuous satellite predictions while eGPS provides a locally generated source of fine time and frequency aiding. Together these technologies significantly reduce time-to-fix and increase GPS sensitivity. This helps maintain optimal GPS performance, even outside of network coverage when time to fix is paramount. As a result of this partnership, CSR and Rx Networks now offer OEM customers the lowest cost and most resilient GPS solution for Personal Navigation Devices (PNDs) and mobile handsets that yield the longest battery life and the fastest, near-ubiquitous performance.
