It uses Real-Time Kinematics, where the stationary base station sends correction data to the moving rover to reduce common GNSS errors and deliver centimetre-level positioning.The kit is designed to work out of the box, with the LoRa correction data link already integrated and pre-configured. The 915MHz LoRa radio link can reach up to 1.5 kilometres in open areas, so you can work without separate radio modems or internet-based NTRIP services.Powered by Quectel LC29H series GNSS modules, the system supports dual-band L1/L5 reception and the GPS, GLONASS, Galileo, BDS and QZSS constellations. The RTK mobile module provides I2C / UART output via a Gravity interface, making it suitable for robotics, UAVs, mapping, tracking and research builds.The package includes RTK Base Station × 1, RTK Mobile × 1, GNSS Antenna × 2, TX915-JKD-20 LoRa Antenna × 2, Flathead Screwdriver × 1, Plug-in Terminal Block DB2EK-3.81-2P-GN-S (Female) × 1 and PH2.0-4P Connection Cable (30cm) × 1.
