The C631 is Hemisphere’s all-new multi-GNSS, multi-frequency smart antenna. The C631 provides robust performance and high precision in a compact and rugged package. With multiple wireless communication ports and an open GNSS interface, the C631 can be used in a variety of operating modes. The built-in web user interface (WebUI) can be used to monitor and control the receiver status and operation, as well as to upgrade the C631 with new firmware and activations.

The C631 GNSS receiver is powered by Athena RTK technology. With Athena, C631 provides state-of-the-art RTK performance when receiving corrections from a static base station or network RTK correction system. C631 delivers centimetre-level accuracy with virtually instantaneous initialisation times and cutting-edge robustness in challenging environments.

Excavator grade metrix
Two ways to play

Use the C631 as a precise base station sending RTK to your existing rover network, or turn the C631 into a lightweight and easy-to-use rover by connecting it to your base via UHF radio or Wi-Fi network.

Powered by Athena GNSS

The C631 provides best-in-class, centimeter-level RTK. Tested and proven with long baselines, in open-sky environments, under heavy canopy, and in geographic locations experiencing significant scintillation, Athena excels in virtually every environment where high-accuracy GNSS receivers can be used.
