The CORVON RTK-11 Kit-s is a high-precision positioning solution built for demanding scenarios such as precision measurement, surveying & mapping, and smart agriculture. It pairs a Ground Base Station (RTK-11-B) with a Sky Rover (RTK-11-Rs) over a LoRa data link, delivering fast, plug-and-play, centimetre-level accuracy of 1 cm + 1 ppm with stable, reliable performance. Dual-frequency RTK across GPS, GLONASS, Galileo, BeiDou and QZSS, ultra-high −164 dBm sensitivity, a 10 Hz update rate and standard NMEA-0183 / UBX output make it a drop-in fit for UAVs, robots and automated machinery.
- Plug-and-Play — pre-configured base & rover
- Survey-Grade Accuracy — dual-frequency RTK, 1 cm + 1 ppm
- Real-Time Dynamic — 10 Hz update for mobile mapping & UAVs
- Robust Anti-Interference — tracking sensitivity to −164 dBm
- Standard Interfaces — NMEA-0183 & UBX over UART
- High-Gain Active Antenna — stable GNSS reception
- Long-Range Link — LoRa data link up to 10 km, unobstructed
- Multi-System Support — GPS · GLONASS · Galileo · BeiDou · QZSS

Thank you for choosing a CORVON product. Please read this disclaimer carefully — by using this product you acknowledge and agree to the following. 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.
Place the Ground Base Station on a stable, open site with a clear view of the sky and away from buildings, trees, high-power radio transmitters and other RF or magnetic sources to avoid multipath and interference. Keep the antenna facing up. Observe correct wiring and polarity — reversed or mis-wired connections can permanently damage the unit. Allow the receiver a clear-sky cold start to reach an RTK fix before relying on its position output for flight.
