Quectel LG69T series features the fifth generation of STMicroelectronics® positioning receiver platform with 80 tracking channels and 4 fast acquisition channels. Its dual band (L1 + L5 or L1 + L2) variants support up to 4 concurrent global constellations (GPS, GLONASS, Galileo and BDS), as well as QZSS, and optionally integrate RTK and Dead Reckoning technology enabling the best performance in various applications.

LG69T (AA) includes an integrated IMU and provides GNSS raw data as well as IMU raw data to use with external positioning engines. LG69T (AB) is an ASIL-B GNSS raw data module used with an external positioning engine and external IMU for functional safety autonomous driving applications. Integrating an internal IMU and fusion engine, LG69T (AF) provides PVT (DR) output as well as high update rate IMU raw data.

LG69T (AI) supporting L1 + L2 bands and LG69T (AJ, AR) supporting L1 + L5 bands are extended temperature GNSS raw data modules. LG69T (AJ) also incorporates an IMU and provides IMU raw data suitable to use with external positioning engines.

LG69T (AM) excludes the IMU and is suitable as a stand alone RTK Rover capable of centimeter-level precision. LG69T (AP) has a built-in automotive grade IMU whereas LG69T (AQ) contains an industrial grade internal IMU, both of which provide DR + RTK centimeter-level performance. LG69T (AS) is suitable as a stand alone or networked RTK base station and provides RTCM output to be used across radio or cellular links.

Navigation rate up to 10 Hz makes the LG69T series suitable for applications such as drones, delivery robots, precision agriculture, mining and marine, automotive telematics as well as ADAS and DMS.
