CSR recently demonstrated its new SiRFusion positioning platform and SiRFstarV architecture on-site, demonstrating the future of indoor positioning and navigation technology. These two products are scheduled to be launched next year. Using a smartphone with the new SiRFstarV architecture, CSR demonstrated to participants how this ground-breaking self-learning platform “fused†location information from multiple technologies for highly reliable and accurate indoor positioning and navigation. .
CSR Chief Marketing Officer and SiRF founder Kanwar Chadha said: "SiRFusion platform and SiRFusion positioning architecture are our latest developments, and promote the mainstream customer experience by using a variety of support-oriented services and seamless integration of indoor and outdoor applications. A goal. With today's release, combined with the SiRFusion platform for mobile devices and the SiRFusion positioning architecture, and the SiRFprimaII SoC for automotive automotive entertainment information products, CSR demonstrates its leadership and position to take positioning technology to a new level. â€
The SiRFstarV architecture introduces a new approach to positioning and navigation. Unlike GPS-only positioning, the SiRFstarV architecture collects real-time information from a variety of technologies: GPS, Galileo, GLONASS and Beidou satellites; multiple RF systems such as Wi-Fi® and cellular networks; and a variety of MEMS sensors Such as accelerometers, gyroscopes and compasses. The SiRFstarV architecture then uses the SiRFusion platform to combine these real-time information with ephemeris data, graphics, cellular base stations, Wi-Fi access point location data, and other cloud-based ancillary information.
Ahmet Alpdemir, senior vice president of CSR's mobile business unit, said: "Our customers are looking for positioning technology that meets the growing demand for location-related applications, and indoor positioning and navigation is the key to these applications. SiRFstarV architecture And the SiRFusion platform will help our customers differentiate their devices by using location services to provide consumers and businesses with an enhanced user experience."
Thirty years ago, using satellite positioning technology for an outdoor positioning often took several minutes, and even when the user was stationary, the measurement error could reach as much as a mile. High-precision outdoor navigation, updated every second, has become a common technology. Similarly, it has taken several seconds to perform an indoor positioning using Wi-Fi technology, and its accuracy is relatively low, while positional deviation (jitter) is high. By combining real-time Wi-Fi and satellite positioning information, pedestrian location estimation (using MEMS sensors), crowd source location, and ancillary data from cloud servers, SiRFusion technology enables faster and more accurate indoor positioning, making continuous indoor navigation a daily Part of life. â€
Dave Huntingford, Director of Product Management at CSR's Mobile Business Unit, said: "Unlike other systems that require manual measurements to build and maintain indoor Wi-Fi and cellular location databases, CSR Location Center (CPC) cloud servers can receive user equipment wirelessly. Anonymous and proactive location information, even indoor information, to improve the database. We have taken a radically new approach to positioning and navigation by combining multiple sources of real-time and cloud-based location information, and Instantly process this information on mobile devices for seamless transition between indoor and outdoor navigation."
The CSR SiRFstarV positioning chip series, which will be released next year, will be the first CSR product to implement and use the SiRFusion platform.
