Quectel Wireless Solutions Co., Ltd., in association with STMicroelectronics, announced the release of the LG69T module, an automotive-grade dual-band high-precision GNSS module that integrates dead reckoning (DR) and real-time kinematic (RTK) technologies.
The new Quectel module, announced at 2019 Apsara Conference in Hangzhou, is designed to facilitate open sky positioning performance with an accuracy of up to 10-centimeters, which is currently the industry’s most advanced positioning technology for the automotive market. LG69T will support next-generation precision positioning capabilities for smart vehicles and autonomous driving scenarios.
The Quectel LG69T GNSS module is based on ST’s STA8100GA, the latest Automotive-grade dual-frequency positioning chip with 80 tracking channels and 4 rapid-acquisition channels that are compatible with many constellations: GPS, BeiDou, Galileo, NAVIC/IRNSS and QZSS. It is an AEC-Q100 qualified dual-band (L1+L5) GNSS module that integrates multi-band RTK technology for centimeter-level accuracy. The LG69T module’s dead reckoning capabilities feature an integrated Inertial Measurement Unit (IMU) that provides continuous high-precision positioning. The LG69T supports corrections input for standard Radio Technical Commission for Maritime Services (RTCM) and centimeter-level navigation by using RTCM data from 3rd-local base stations. The module performs well under the highly challenging conditions of urban canyon environments.
Engineering samples of Quectel’s LG69T module will be offered to automakers and Tier 1 suppliers by the end of 2019, and the product will be commercially available around mid-2020 and is expected to be deployed in mass-produced models as early as 2021.
