GNSS Dual-Band Module Quectel LG69T-AM

GNSS Dual-Band Module Quectel LG69T-AM
  • High precision GNSS module
  • 22.0mm × 17.0mm × 3.15mm
  • 1.9g
  • GPS, QZSS, GLONASS, Galileo and BeiDou
  • Operating temperature range of -40°C to +85°C

The LG69T-AM is an advanced dual band L1/L5 GNSS module supporting RTK with centimeter-level accuracy. The LG69T-AM is an ideal solution for high precision markets including agriculture, robotics and autonomous vehicles. Based on the STMicro Teseo5, the module supports 80 tracking channels and 4 fast acquisition channels, along with advanced RTK algorithms offering sub-10cm horizontal accuracies.

With ultrafast convergence times, the LG69T-AM is capable of consuming standard RTCM corrections from multiple partners, providing the user flexibility depending on application and region. The LG69T-AM, based on AEC-Q100 certified Teseo5 position engine, is manufactured in IATF 16949 qualified locations, under Quectel’s strict Automotive Quality Management system.

The module is designed for easy integration with minimal e-BOM and comes with direct access to Quectel’s extensive support team including development kits, reference designs, design reviews, RF testing, L1/L5 antennas and local base stations.
