ST-Ericsson has launched tiny receiver (claims to be the smallest available) to be able to see both GPS and GLONASS positioning satellites, enabling mobile devices to deliver much faster and much more reliable location-based services.
Compared to GPS-only solutions, the combination of GLONASS and GPS technology dramatically improves positioning accuracy in dense "urban canyon environments", where tall buildings can obscure satellite signals, as well as significantly reducing the time it takes to initially determine a device's location.
Requiring just two external components, the CG1950 is the first GPS/GLONASS receiver to be built in 45 nanometer silicon, enabling manufacturers to produce sleek, low-cost devices capable of supporting highly-accurate navigation, mobile social networking, augmented reality and other location-based services. The low-power device is designed to be integrated into mobile phones, camcorders, cameras and other mobile devices.
The combination of GPS and GLONASS, will enable devices to retrieve positioning data from more than 50 satellites by the end of 2011.
The receiver features -163 dBm acquisition sensitivity and -165 dBm tracking sensitivity with embedded LNA (single-ended antenna), autonomous (cold start) TTFF of < 38 s, and A-GPS (hot start) TTFF of < 1 s. Its low power consumption enables continuous GNSS (Global Navigation Satellite System) tracking for more than 30 hours with a standard 850 mAh battery.
"The frustration of waiting for your device to locate you will be a thing of the past once receivers can connect to both GPS and GLONASS satellites," said Thierry Tingaud, Senior Vice President Entry solutions & Connectivity Division of ST-Ericsson. "This breakthrough will also mean more precise positioning, fueling demand for augmented reality applications and other sophisticated location-based services that depend on very accurate readings."
Set to be in commercial handsets by the third-quarter of 2011, the CG1950 will be available both as a standalone component and integrated into ST-Ericsson complete cellular platforms.
