CSR and Rx Networks partner on eGPS® and Predicted GPS positioning technologies

Combined Solution Optimizes Performance of Low-Cost Software GPS Engine for Growing Array of GPS Devices


Cambridge, UK & Vancouver, Canada – September 11, 2008. CSR (LSE: CSR), a leading global provider of wireless technologies, and Rx Networks, Inc. a private mobile positioning technology and global services company today announced a GPS solution that combines their respective eGPS® 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 unsynchronized GSM and W-CDMA networks or in synchronized 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 15 seconds 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 (PND’s) and mobile handsets that yields the longest battery life and the fastest, near-ubiquitous performance.

“CSR’s eGPS® is an important development in deeper thus more ubiquitous mobile GPS assistance, and eGPS® will flourish as multiple complementary companies support eGPS®. We are happy to join the eGPS® ecosystem which already includes some of our existing customers, partners and prospects” said Richard Lee, EVP Business Development of RX Networks. “Rx Networks’ GPStream™ products and technology are a perfect complement to CSR’s location portfolio and provide an important element for assisting our GPS silicon and eGPS® software products,” said Stuart Strickland VP for CSR’s LBS Business Unit.
