GPStream PGPS™ version 6 offers OEMs unprecedented flexibility and enhancements in accuracy and execution time. Mobile World Congress 2011 Booth: C30, Hall 2.1

Mobile World Congress, Barcelona, Spain– Rx Networks Inc., a leading mobile location technology company, today announced the immediate availability of version 6 of GPStream PGPS™, Rx Networks’ Assisted-Global Navigation Satellite System (A-GNSS) software for mobile devices. PGPS version 6, to be demonstrated during Mobile World Congress, is the industry’s first and only extended ephemeris solution designed to support both disconnected and occasionally connected modes of operation for both the GPS and GLONASS constellations, across multiple GNSS chipsets.

GNSS chips must first acquire satellite information before calculating a position, which can normally take 45 seconds or longer and affects the user experience. Some Assisted-GNSS techniques mitigate this delay by relaying satellite information to devices in real-time, whenever needed. GPStream PGPS™ however predicts the future behaviour of satellites for up to a week and thus eliminates the need for real-time network connectivity. It can preload this predicted information into a wide range of GNSS chipsets to achieve cold starts as fast as 2 seconds. This flexibility enables chipset and mobile device OEMs to address a wide variety of operational scenarios and improve the user’s mobile experience when consuming Location-Based Services. PGPS version 6 also helps mobile device OEMs reduce costs and shorten their product development cycle by supporting assistance data for multiple navigation chipset suppliers through a common GNSS assistance data software stack.

“In version 6, we’ve created a single comprehensive package that combines our unique and patented techniques for providing extended ephemeris GNSS assistance to connected devices regardless of their network connection,” stated Guylain Roy-MacHabée, Rx Networks’ CEO. “We have spent the last 18 months working closely with leading GNSS chipset vendors and device OEMs to design this improved solution and will see it deployed in several leading handsets, laptops, personal navigation devices (PNDs) and pad computers in 2011. This dual-mode, dual constellation product simplifies A-GPS/A-GNSS integration for our customers and improves the mobile location user experience.”

PGPS version 6 represents the most significant enhancements in the capabilities and scope of Rx Networks’ extended ephemeris solutions since their introduction in 2008. Key enhancements include new support for the GLONASS satellite constellation, better extended ephemeris accuracy, two to five times execution speed improvement, and support for single-threaded operating environments. In addition, PGPS version 6 now adds the autonomous capability previously found in the stand-alone GPStream SAGPS™ product. Regardless of network connectivity, this dual-mode feature enables PGPS to always deliver the best available extended ephemeris by seamlessly adapting between server-seeded and autonomously-generated predictions.
