Description
The GNSS-RTK High Precision Positioning Kit provides an out-of-the-box centimetre-level navigation solution using a stationary base station and mobile rover. Featuring a pre-configured 868 MHz LoRa wireless link, it eliminates complex communication setup for rapid field deployment. It is ideal for students, hobbyists, and developers working on autonomous robotics, drone navigation, and geospatial surveying.
Centimetre-level RTK accuracy
Powered by Quectel LC29H series modules, the kit achieves an RTK Fixed positioning accuracy of up to 5 cm + 1 ppm by applying real-time differential corrections. This carrier-phase processing delivers high repeatability and precision, far surpassing standard single-point GNSS receivers.
Pre-configured long-range LoRa link
The base station transmits RTCM correction data to the mobile rover via an integrated 868 MHz Semtech LLCC68 LoRa transceiver. This factory-configured link delivers reliable wireless communication up to 1.5 kilometres in open areas without requiring manual data link configuration.
Dual-band multi-constellation tracking
The system tracks concurrent dual-band (L1/L5) signals across GPS, GLONASS, Galileo, BDS, and QZSS constellations. This broad satellite support enables rapid signal acquisition, sub-10-second RTK convergence times, and robust tracking in challenging environments.
Versatile interfacing and power options
The mobile rover connects directly to microcontrollers via standard I2C or UART interfaces powered by 3.3V to 5V on a Gravity connector. The base station accepts 5V to 10V power via a plug-in terminal block or USB Type-C and outputs standard NMEA 0183 and RTCM 3.x protocols.
Built for robotics and surveying
With a 1 Hz RTK navigation update rate and robust dynamic handling up to 4g acceleration, the kit is suitable for precision agriculture, UAV navigation, and boundary mapping. It includes all necessary GNSS and LoRa antennas, mounting cables, and connectors for immediate deployment.
