Rx Networks Announces GPStream Self-Assisted GPS Extended Ephemeris Solution

Fully Autonomous Open Architecture Delivering Click’n Go™ Performance For Any GPS Device.

Vancouver, BC, Canada, January 28, 2008 — Rx Networks, Inc., a leading Assisted-GPS (AGPS) technology and global services company, today announces a fully autonomous extended ephemeris AGPS product. GPStream™ SAGPS™, Self-Assisted GPS technology, is an open architecture solution designed to reduce start up times of GPS devices and to deliver a “Click’n Go” user experience without the need for a network connection or downloads.

“GPStream SAGPS is primarily targeted for use in stand-alone GPS devices with little or no external communications capabilities, such as Personal Navigation Devices (PND) or in-vehicle systems” said Guylain Roy-MacHabée, President and CEO of Rx Networks. “However, in line with our vision to enable the best GPS user experience anytime, even GPS-enabled phones or PDAs can rely on GPStream SAGPS to maintain fast time to first fix when standard assistance data downloads are unavailable.”

Knowledge of satellite positions in the future makes AGPS products fast; and this solution enables mobile devices to model the behavior of individual GPS satellites in order to predict satellite positions up to 5 days into the future. This means that GPStream SAGPS can help any GPS device resolve its initial position in as little as 3.5 seconds. After only one broadcast ephemeris reading, SAGPS accurately predicts satellite orbits, then continuously develops and refines prediction data every time new broadcast ephemeris is obtained. GPStream SAGPS is the only autonomous GPS assistance data solution optimized for any device and any chipset architecture.

Open Architecture
Design once and Reuse: GPStream SAPS is chipset, device, operating system and network agnostic. This platform independence means semiconductor platform suppliers and GPS device manufacturers can use GPStream SAPS uniformly across families of GPS receivers

AGPS Performance
GPStream SAPS is highly accurate and capable of predicting GPS satellite positions for up to 5 days into the future while maintaining street level accuracy. Alternative solutions tend to sacrifice the street level precision required by most applications in order to attain a fast first fix.

Ongoing Availability
Running as a low-priority background task, GPStream SAGPS is uniquely capable of synthesizing prediction data from a single broadcast ephemeris reading, limiting the amount of time the system has to operate before assistance data is available.

Easy Integration
GPStream SAGPS is operating system independent and comes with a simple API command set for easy integration.

Interoperability And Extensibility
For connected devices, GPStream SAGPS can seamlessly interoperate with other sources of broadcast ephemeris such as a SUPL client. Adding GPStream SAGPS to traditional real time assistance solutions reduces network overhead, enables Click’n go performance even out of network coverage, and reduces Time To First Fix by a further 5 to 10 seconds.

About GPStream Mobile Suite
The GPStream SAGPS mobile client software is part of the GPStream Mobile Suite. Although it can operate stand alone, GPStream SAGPS can also seamlessly work with other GPStream Mobile Suite building blocks to form a complete AGPS solution that can deliver different forms of assistance in any GPS device. The GPStream Mobile Suite includes: GPStream SUPL™, a Secure User Plane client with extended ephemeris capability; GPStream GROAM™ Global initial position assistance for GPS devices, and GPStream PGPS™, a predicted GPS extended ephemeris solution for network connected devices. All these building blocks share a common integration interface and data base structure for easy integration, interoperation, and migration.

About Rx Networks
Rx Networks is a mobile positioning technology and global services company. With GPStream™, a complete framework of GPS assistance solutions, Rx Networks enables Click’n Go™ performance for any GPS device. Rx Networks represents the “A” in AGPS.
