The CORVON RTK-12 Kit-s is a quad-constellation, multi-frequency RTK positioning system that pairs a Ground Base Station (RTK-12-B) with a dual-antenna Sky Rover (RTK-12-Rd) for centimetre-level 3D positioning and heading. The base delivers ultra-high −165 dBm sensitivity and on-chip multi-frequency RTK of up to 0.8 cm + 1 ppm over a LoRa link, while the dual-antenna rover adds a full-constellation moving-baseline heading solution. NMEA-0183 / UBX output and standard RTCM 3.X corrections make it a drop-in reference for drones, vehicles, vessels and survey work.

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.
Install the base-station whip antenna before powering on — powering the base without the antenna can permanently damage the chip; use a power adapter rated 2 A or higher. Place the base on a stable, open site with a clear view of the sky, away from buildings, trees and strong RF or magnetic sources, antenna facing up. On the rover, keep the two GNSS antennas (primary / secondary) at least 30 cm apart for a reliable heading solution. Observe correct wiring and polarity on the GH1.25 connectors — reversed or mis-wired connections can permanently damage the module.
