MediaTek Announces Multi-GNSS Receiver SoC Solutions Supporting Beidou

January 28, 2013  - By

MediaTek Inc., a fabless semiconductor company for wireless communications and digital multimedia solutions, today announced the availability of its MT3332/MT3333, a 5-in-1 multi-GNSS receiver system-on-chip (SoC) that support the Beidou Satellite Navigation System. The Beidou system has been commercially operational since the end of 2012, and can identify a user’s location to 10 meters (33 feet), their velocity to within 0.2 meters per second, and clock synchronization signals (one-way) to within 10 nanoseconds.

The MediaTek MT3332/MT3333 can discover GPS, Beidou, GLONASS, Galileo and QZSS constellations. Featuring a multi-GNSS receiver design, the MT3332/MT3333 can reduce the cumulative distance and positioning error accumulated over time/multiple hops, and significantly improve navigation/positioning accuracy, MediaTek said. The MT3332/MT3333 also comes with excellent signal acquisition and tracking sensitivity, which efficiently enhances signal quality within dense cities, tunnels and multi-storey car-parks, while delivering a better user experience, the company said. Moreover, because of its highly integrated, low-cost and ultra-compact system architecture, the MT3332/MT3333 enables multi-GNSS receivers with the same reference board for mobile, industrial and automotive navigation applications.

“The proliferation of LBS (location-based services) using mobile applications over wireless networks such as social check-in or nearby service recommending is driving demand for greater satellite navigation performance and coverage beyond existing technologies. This will also lead to the rapid adoption of multi-GNSS receiver solutions in smartphones, tablets and automotive vehicles because LBS is now an indispensable way for people to interact/communicate with each other on a daily basis,” said SR Tsai, general manager of the Wireless Connectivity and Networking Business Unit at MediaTek. “We believe the market for Beidou-compatible multi-GNSS receivers in China will accelerate in the coming years. MediaTek will deliver new products that offer high value and are capable of meeting the evolving needs of our customers in the Beidou navigation system market through continuous product innovation. The MT3332/MT3333 [models] are designed to accelerate the realization of satellite navigation services anytime, anywhere, in a seamless fashion.”

The MT3332/MT3333 also incorporates MediaTek’s unique “AlwaysLocate” technology that can identify the state in which the user is (regardless of on-the-go or sleeping) and automatically adjust the satellite signal receiving modes for more accurate and reliable navigation services, and to save the battery power of the navigation system.

The MediaTek MT3332/MT3333 is now in mass production stage and being designed into major satellite navigation systems and mobile communication platforms worldwide.
