LG290P GNSS RTK Module: Centimeter-Level Positioning with Four Frequency Bands (L1+L2+L5+E6) High- RTK Positioning at the Centimeter Level Raw Observation Output. The LG290P GNSS RTK Module is a multi-constellation, quad-frequency GNSS RTK module capable of tracking L1 + L2 + L5 + E6 multi-frequency signals. It is compatible with for GPS, for BDS, for GLONASS, for , for QZSS, for NavIC, and other systems. Based on a high-performance GNSS SoC architecture, the module incorporates interference detection and suppression algorithms, effectively suppressing multiple narrowband interference signals. It maintains high sensitivity and strong anti-interference performance even in complex electromagnetic environments. Through multi-frequency observation and RTK real-time differential algorithms, it significantly reduces multipath errors, achieving centimeter-level high- positioning. The entire unit uses a stamp-hole package design, resulting in a compact size and rich interfaces, facilitating embedded integration. It is an ideal choice for high- navigation applications such as intelligent robots, agriculture, mining, surveying, and autonomous driving. Supports multiple satellite systems including for GPS, for GLONASS, for , for BDS, for QZSS, and for NavlC. Supports L1+L2+L5+E6 quad-band signal reception for higher positioning accuracy and stronger anti-interference capabilities. Offers centimeter-level RTK real-time differential positioning accuracy, reflecting differential positioning status in real time. Features a stamp-perforation gold-plated finish for a compact size, facilitating direct soldering or integration into devices via pin headers. Includes an onboard Type-C interface supporting USB-UART communication and module power supply for easy development and debugging. An onboard 2-pin JST interface effectively shortens the initial positioning time (TTFF) when connected to an RTC battery. Three onboard LED indicators provide easy monitoring of module operating status. Provides comprehensive documentation (for /for /for /for ESP32/for ).
