LG290P Series - Quad-frequency RTK Centimeter-level Positioning GNSS Expansion BoardAdopts L1+L2+L5+E6 quad-frequency positioning technologySupports concurrent reception of multiple satellite systems

The LG290P GNSS RTK Module is a multi-constellation, quad-frequency GNSS RTK module. It tracks multi-frequency signals (L1 + L2 + L5 + E6) and is compatible with satellite systems including GPS, BDS, GLONASS, Galileo, QZSS, and NavIC.Built on a high-performance GNSS SoC architecture, the module integrates in-built interference detection and suppression algorithms. It effectively mitigates multiple narrowband interference signals, maintaining high sensitivity and strong anti-interference performance even in complex electromagnetic environments. Through multi-frequency observations and RTK real-time differential algorithms, it significantly reduces multipath errors, enabling centimeter-level high-precision positioning.Featuring a stamp hole package design, the module boasts a compact size and rich interfaces for easy embedded integration. It is an ideal choice for high-precision navigation applications such as intelligent robots, precision agriculture, mining, surveying and mapping, and autonomous driving.

Either set up a continuously operating reference base station using the LG290P module configured in base station mode at a ground location with known fixed coordinates, or purchase RTK ground-based augmentation services. GNSS correction values are sent via the network to the LG290P rover that has uploaded rough positioning information, and the terminal device—affected by errors such as multipath refraction—performs real-time error calculation to achieve centimeter-level positioning within seconds.
