CSR has announced that it is exhibiting new SiRFusion location platform and SiRFstarV architecture at Mobile World Congress 2012.
STMicroelectronics and CSR will demonstrate how the advanced SiRFusion platform fuses sensor inputs, radio signals and other related location information using a smartphone that has STMicroelectronics’ MEMS sensors and a pre-production SiRFstarV device to make precise and consistent indoor navigation and location.
During the live demonstration, the MEMS sensor module from STMicroelectronics was used. This module is a multi-sensor inertial measurement unit that unites three axis angular, linear and magnetic motion sensing with pressure readings. These readings are utilized to find the elevations of multi-story buildings, so that the position can also be determined.
The SiRFstarV architecture provides a new path for navigation and location. It collects the real-time data to find the position rather than relying only on GPS. This data is gathered from Galileo, GPS, compass satellites, glonass, MEMS sensors such as compasses, gyro and accelerometers, and various radio systems like cellular and Wi-Fi. Then, this real-time data is combined with cellular base station, ephemeris data, Wi-Fi access point location data, mapping and cloud-based aiding data through the SiRFusion platform.
Indoor applications from VisioGlobe and Whatamap.com are loaded in a mobile handset that integrates the MEMS sensors and SiRFstarV architecture, in order to demonstrate the SiRFusion indoor navigation power. These applications demonstrate the indoor positioning, walking directions and search with Micello and Navteq’s high-quality indoor maps.
