Rx Networks Announces New Version of Its GNSS Extended Ephemeris Solution

June 10, 2019



Rx Networks Inc., a leading mobile location technology and services company, today announced the upcoming release of its GPStream PGPS™ v8 extended ephemeris solution. This patented technology, already proven in hundreds of millions of devices, is designed to speed up the Time-To-First-Fix (TTFF) of any GNSS chipset while improving acquisition sensitivity in challenging environments.

Compared to its previous version, GPStream PGPS™ v8 effectively doubles the accuracy performance while supporting all four global GNSS constellations, making it the industry leading extended ephemeris solution. GPStream PGPS™ v8 will be available for integration testing in Q2 2015, with commercial release in Q4 2015 (full commercial support for Galileo will remain subject to the readiness of the constellation).

All major GNSS semiconductor vendors are now offering or developing multi-constellation support in order to improve availability in challenging environments. Quad-constellation support also enables OEMs and GNSS chipset manufacturers to meet any national or regional market requirement. Availability of extended ephemeris across the four constellations is required to ensure fast TTFF and optimal sensitivity. Early lab access to the latest GPStream PGPS™ v8 solution from Rx Networks can help chipset manufacturers validate performance early in the development cycle and thus accelerate the time to market for their new multi-constellation chipsets.

A key component of any extended ephemeris solution is the accuracy of the orbit and clock predictions. This accuracy is often presented as an error in meters compared to the native Broadcast Ephemeris that is transmitted by the satellites. The latest version of GPStream PGPS™ improves this accuracy by a factor of two, compared with its prior release. For example, day 1, 7 and 14 accuracies for GPS are now 2.8m, 4.5m and 11.4m compared to 6.3m, 12.5m and 30.2m previously. BeiDou and Galileo will experience similar performance. GLONASS is also significantly improved, with day 1, 7 and 14 accuracies of 1.8m, 6.5m and 13.7m compared to 7.3m, 13.4m and 27.2m previously.

“Rx Networks continues to expand its relationships with major OEMs and GNSS chipset manufacturers to help them deliver innovative, multi-constellation and highly accurate GNSS performance,” said John Carley, Sr. Product Manager at Rx Networks. “This latest release reaffirms our commitment to provide best in class Assisted-GNSS solutions for the mobile market.”
