More GNSS for your money
The C631 is Hemisphere’s all-new multi-GNSS, multi-frequency smart antenna. It 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. Turn the C631 into a lightweight and easy-to-use rover by connecting it to your base with the built-in dual-band radio via UHF 450-470 Mhz or 900 Mhz. You can even connect by Wi-Fi network or by cell modem.
The C631 receiver is powered by Athena RTK technology providing state-of-the-art RTK performance when receiving corrections from a static base station or network RTK correction system. The C631 delivers centimeter-level accuracy with virtually instantaneous initialization times and cutting-edge robustness in challenging environments. It is also capable of receiving corrections with Atlas. Atlas is Hemisphere’s industry-leading global correction service, which can be added as a subscription. Atlas delivers worldwide centimeter-level correction data over L-band communication satellites. With Atlas, users can experience sub-decimeter positioning performance anywhere on earth, without the need to be near a GNSS or communication infrastructure.
All 631 units come with the most powerful tilt compensators in the industry. No calibration required for this receiver, just shake the rod back and forth for a few seconds (when needed) and your tilt is ready to go. Go out as far as 30 degrees.
The built-in web user interface (WebUI) can be used to control and manage the receiver status and operation, as well as to upgrade the C631 with new firmware and activations.
