Overview
The LG69T is an AEC-Q100 qualified dual-band GNSS module measuring 22.0mm × 17.0mm × 3.3mm, with integrated multi-band RTK technology for centimeter-level accuracy. The module features the STMicroelectronics® 5th generation positioning receiver platform with 80 tracking channels and 4 fast acquisition channels, compatible with up to 5 constellations: GPS, GLONASS, Galileo, BeiDou and QZSS.
The LG69T provides dead reckoning capabilities with an integrated inertial measurement unit (IMU) to provide continual, highly precise positioning. The state-of-the-art integrated algorithms fuse between IMU data, GNSS measurements, wheel ticks and vehicle dynamics model to provide lane-accurate positioning where GNSS alone would fail. The module supports standard RTCM corrections input and centimeter-level navigation by using RTCM data from 3rd party local base stations, allowing it to perform excellently under challenging conditions such as urban canyons.
The LG69T is designed for easy integration with minimal e-BOM and is well-suited for mass market adoption. Due to its compact design, light weight, and low power consumption, it is ideal for vehicle markets such as automotive navigation, ADAS and V2X, as well as applications in precision smart agriculture.
