The CORVON RTK-13 Kit-s is a multi-constellation, dual-frequency RTK positioning kit built around the RTK-13-B base station and the compact RTK-13-Rs rover. The system provides real-time differential corrections over a LoRa data link for centimetre-level 3D positioning, with high sensitivity, low power consumption, and compact hardware for UAVs, unmanned vessels, mapping, agriculture and robotic applications.

- LoRa Link — real-time differential data
- Integrated Compass on Rover — QMC5883
- Dual-Frequency Reception — L1 / L2
- Standard GNSS Output — NMEA-0183 / UBX supported
- On-Board RTK Algorithm — up to 1 cm + 1 ppm
- Active / FPC Antenna Options — matched to base and rover

Thank you for choosing a CORVON product. Please read this disclaimer carefully before using the RTK-13 Kit-s. Because we cannot control how this product is installed, used, or maintained, we accept no liability for any loss or damage arising from its use, and any unauthorized modification is undertaken at your own risk.
Install the base-station whip antenna before powering on; powering the base without the antenna may permanently damage the chip. Use a power adapter rated above 2 A. Place the base in an open, unobstructed location with a clear view of the sky, away from strong RF sources, high-voltage power lines, large water surfaces and metal reflectors. Before connecting the RTK-13-Rs, power off the flight controller, verify the GH1.25-6P cable orientation, and keep the rover compass direction aligned with the aircraft heading. Reversed wiring or incorrect polarity can permanently damage the module.
