GNSS
ST-Ericsson Global Navigation Satellite Systems (GNSS) solutions can be found inside numerous devices and our legacy with the technology dates back to 1983 when we first introduced GPS devices to the market. ST-Ericsson has also worked in close cooperation with the US government towards the launch of the NAVSTAR, today commonly referred to as GPS.
The market for location technologies continues to grow from PND’s (Personal Navigation Devices) for navigation, to cellular phones (navigation, E911, location based services), to consumer electronics with features such as geotagging, video recording and now to social networking. The penetration rate for GPS in smartphones is already 100% and will continue to expand into other segments. We expect that 4 out of 5 phones shipping in 2014 will be location aware.
Glonass for increased localization performance
Devices providing location continue to focus on adding an ever increasing set of constellations to provide better user-experience in urban canyons, better accuracy and user location. And combined with other technologies like Wi-Fi, sensors, and Bluetooth it can offer always-on and everywhere location services. ST-Ericsson is adding GLONASS hardware for our GNSS products to increase localization performance in dense urban areas (Urban Canyon) and ways to improve multipath degradation which is today the biggest source of error in the GNSS receiver. GLONASS support offers the ability to see more satellites in the sky than just GPS satellites. With more satellites visible, one can easily decode the co-ordinates and time equation to get an accurate position.
proven and Verified GNSS solutions
ST-Ericsson has close operator partnerships to ensure proven and verified GNSS products that deliver excellent A-GNSS performance. By continuing to evolve our algorithms and using hybrid techniques, coupled with the close link between the modem and GNSS devices for AGNSS, ST-Ericsson offers a fully pre-integrated phone reference solution for quick product launch.

What is GNSS, GPS, GLONASS?
GNSS (Global Navigation Satellite System) is the generic term used to describe satellite based technology to provide user location.
GPS (Global Positioning System), a satellite navigation system maintained and operated by the United States government.
GLONASS, a satellite navigation system operated by the Russian Space Forces. GLONASS can be used as alternative to the other GNSS or as a complementary to them for better coverage and higher measurement precision..
