Features at a glance
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.
