MediaTek introduces multi-GNSS receiver SoC solutions for Beidou system

Feb 07, 2013 (Datamonitor via COMTEX) -- MediaTek Inc., a fabless semiconductor company, has announced the availability of MT3332/MT3333, its multi-GNSS, or global navigation satellite system, receiver SoC, or system on chip, solutions that support the Beidou Satellite Navigation System.

The Beidou system has been commercially operational since the end of 2012, and is currently a constellation of 16 satellites providing positioning, navigation and timing services to the Asia-Pacific region. It can identify a user's location to 10m (33ft), 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 improve navigation/positioning accuracy, the company said.

According to the company, the MT3332/MT3333 also come with excellent signal acquisition and tracking sensitivity, which enhances signal quality within dense cities, tunnels and/or multi-storey car-parks.

SR Tsai, General Manager of the Wireless Connectivity and Networking Business Unit at MediaTek, said: "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.

"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 are designed to accelerate the realization of satellite navigation services anytime, anywhere, in a seamless fashion." The MT3332/MT3333 also incorporate MediaTek's "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 accurate navigation services, and to save the battery power of the navigation system, the company concluded.
