BeiDou, Dead Reckoning Added to SiRFstarV 5ea Auto Platform

November 24, 2014  - By

CSR plc has released significant upgrades for the SiRFstarV 5ea automotive-grade quad-GNSS location platform. Support has been added for concurrent use of GPS and BeiDou (BDS) satellite constellations, along with major updates to the SiRFDRive software dead-reckoning algorithms. Together, these upgrades ensure that SiRFstarV 5ea offers improved automotive positioning performance meeting the requirements of OEMs across the globe.

CSR is being acquired by Qualcomm, with the transaction expected to close by the end of the summer of 2015.

By adding support for China’s BDS constellation to SiRFstarV 5ea’s existing GPS and GLONASS capabilities, the new software offers automotive OEMs the flexibility to perform concurrent GPS and GLONASS or GPS and BDS operations. The new BDS capability provides OEMs the opportunity to market their products to regions where BDS support is mandated and also exploit the benefits of the BDS satellite constellation which is now fully operational over China and surrounding countries. The SiRFstarV 5ea platform, which is optimized and certified for the strict requirements and life cycles of the automotive industry, is also Galileo-ready through future software upgrades.

“Automotive OEMs from around the globe all have something to gain from the new additions to our cutting-edge SiRFstarV 5ea automotive location platform,” Anthony Murray, senior vice president, Business Group, at CSR, said. “Tier Ones and OEMs are looking to develop global platforms that can be easily configured to meet regional requirements and preferences, while Asian car manufacturers in particular have been calling for simultaneous GPS and BDS support to meet regional market needs for BDS support.”

SiRFDRive for SiRFstarV 5ea now also includes CSR’s latest dead reckoning algorithms that work alongside concurrent GPS and GLONASS operations. The combination of increased satellite visibility and the latest dead-reckoning algorithms improves the overall performance in challenging environments such as Chicago and Tokyo by a factor of two.

“Many Tier Ones are looking for more complete dead reckoning solutions to simplify the design process and accelerate time to market. SiRFDRive is a state-of-the-art plug-and-play solution that covers a range of end products spanning from low to high end telematics and navigation systems,” continued Murray.

SiRFstarV 5ea is designed for automotive market AEC-Q100 qualification requirements as a standalone location engine platform. The platform provides automotive Tier One suppliers and OEMs around the world with continuous, highly accurate positioning capabilities for the next generation of in-dash navigation and telematics applications in cars, trucks and other moveable assets requiring automotive-qualified devices.

Updated SiRFstarV 5ea evaluation kits are available now, and the SiRFstarV 5ea platform is ready for immediate integration into next generation infotainment and telematics products.
