The LG69T from Quectel is a dual-band GNSS module that supports six constellations: GPS, GLONASS, Galileo, BeiDou, QZSS, and NAVIC (former IRNSS). It has multi-band RTK technology that enables centimeter-level accuracy. The module is based on the 5th generation STMicroelectronics® positioning receiver platform that has 80 tracking channels and 4 fast acquisition channels.
The module includes dead-reckoning capabilities and an integrated inertial measurement unit (IMU) which provides high-precision positioning. The state-of-the-art integrated algorithms fuse between the IMU data, GNSS measurements, wheel ticks, and vehicle dynamics model to provide accurate positioning in areas where GNSS alone would fail. It supports standard RTCM correction input, as well as centimeter-level navigation by using RTCM data from 3rd party base stations. The module preforms exceptionally well under challenging environmental conditions, such as urban canyons.
The LG69T is available in a package that measures 22.00 x 17.00 x 3.15 and is ideal for vehicle markets, such as automotive, ADAS, V2X, and precise agriculture applications. It operates over a supply voltage of 3.3 V.
