The LoRa-Based GNSS-RTK High Precision Positioning Kit (US) is a comprehensive, dual-module system engineered to deliver centimeter-level location accuracy. It operates on the principle of Real-Time Kinematics (RTK), which involves a stationary base station transmitting correction data to a mobile rover, effectively eliminating common GNSS positioning errors. The kit's key differentiators are its out-of-the-box functionality with a pre-configured LoRa data link, its high-performance dual-band GNSS reception, and its rapid convergence time. Powered by Quectel LC29H series modules, the system supports GPS, GLONASS, Galileo, BDS, and QZSS constellations, making it a robust solution for demanding applications such as autonomous vehicle navigation, land surveying, and device tracking.

Out-of-the-Box, Centimeter-Level Accuracy
This GNSS-RTK positioning kit is designed to significantly lower the barrier to entry for high-precision positioning. Traditional RTK systems often require users to independently source and configure separate modules for the base, rover, and data transmission link. This product integrates all necessary components into a pre-configured, ready-to-use solution. Users can achieve centimeter-level accuracy within minutes of setup, bypassing the complex integration and debugging process typically associated with RTK technology.

High-Performance Dual-Band GNSS Engine
At the core of the system are the Quectel LC29H series modules, which feature dual-band (L1/L5) reception. This advanced capability allows the receiver to effectively mitigate ionospheric disturbances, a primary source of error in single-band receivers. The result is a significantly faster convergence time (less than 10 seconds to achieve a fixed solution) and more reliable and consistent positioning accuracy, even in challenging signal environments. Simultaneous tracking of all major satellite constellations ensures maximum satellite availability and positional integrity.
Integrated Long-Range LoRa Data Link (915 MHz US Version)
A stable data link is critical for RTK performance. This GNSS-RTK positioning kit incorporates a LoRa (Long Range) radio communication system to ensure robust and reliable transmission of correction data from the base station to the rover. This integrated wireless solution provides a communication range of up to 1.5 kilometers in open areas, eliminating the need for external radio modems or reliance on internet-based NTRIP services. This self-contained architecture makes the kit ideal for fieldwork and applications in areas with limited network connectivity.
