Telecom Lead Asia: MediaTek has announced its 5-in-1 multi-GNSS (Global Navigation Satellite System) receiver SoC solutions support the Beidou Satellite Navigation System.
The Beidou system 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.
In addition, the MT3332/MT3333 can reduce the cumulative distance and positioning error accumulated over time/multiple hops, and improve navigation/positioning accuracy. 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, while delivering better user experience.
“The proliferation of LBS (location-based services) using mobile applications over wireless networks 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.
The MT3332/MT3333 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 more accurate and reliable navigation services, and to save the battery power of the navigation system.
The MediaTek MT3332/MT3333 are currently in mass production stage and already being designed into major satellite navigation systems and mobile communication platforms worldwide.
