GNSS Module
Quad-band L1+L2+L5+E6 | RTK centimeter-level Accuracy | Raw Observation data output
The LG290P GNSS RTK Module is a quad-band, multi-constellation GNSS RTK module that supports the L1, L2, L5 and E6 frequency bands, compatible with GPS, BDS, GLONASS, Galileo, QZSS and NavIC satellite systems. Based on a high-performance GNSS SoC architecture, it integrates professional-grade interference detection and cancellation algorithm to effectively mitigate multiple narrow-band interferences, maintaining high sensitivity and strong anti-jamming performance even in complex electromagnetic environments. Through multi-frequency observations and RTK real-time differential algorithm, it significantly reduces multipath errors and enables centimetre-level high-precision positioning.
Small size with castellated holes design, it features a rich set of interfaces, and is easy to integrate, making it an ideal choice for high-precision navigation applications such as intelligent robots, precision agriculture, mining, surveying and mapping, and autonomous driving.

- Quad-band reception (L1 + L2 + L5 + E6) for higher positioning accuracy and stronger anti-interference performance
- Centimeter-level RTK real-time differential positioning, with real-time status reporting of differential positioning
- Castellated holes with immersion gold design, small size, easy to integrate into the device by soldering directly or inserting via the pin header
- Onboard Type-C port supporting UART to USB communication and module power supply, enabling easy development and debugging
- Onboard 2-pin JST connector for connecting an RTC backup batt., effectively reducing Time to First Fix (TTFF)
- Onboard 3 LED indicators for module operating status
- Comes with online development resources and manual (examples for Raspberry Pi / Raspberry Pi Pico / Jetson Orin / ESP32 / Arduino)
