The C631 is Hemisphere’s brand new intelligent multi-GNSS multi-frequency antenna. The C631 offers robust performance and high precision in a compact and robust housing. With multiple wireless communication ports and an open GNSS interface, the C631 can be used in a variety of operating modes. Use the C631 as a precise base station that transmits RTK to your existing rover network. Turn the C631 into a lightweight and easy-to-use rover by connecting it to your base via UHF radio or a Wi-Fi network. You can use the integrated web user interface (WebUI) to control and manage the status and operation of the receiver and update the C631 with new firmware and activations. The C631 is Athena-enabled and Atlas-enabled (subscription required).

The C631 receiver is supported by Athena RTK technology. With Athena, the C631 offers state-of-the-art RTK performance when receiving corrections from a static base station or a network RTK correction system. The C631 has several connection options and enables RTK corrections to be received via radio, cellular modem, Wi-Fi, Bluetooth or a serial connection. The C631 offers centimeter-level accuracy with virtually instant initialization times and state-of-the-art ruggedness in challenging environments.

The C631 receiver also allows you to work with Atlas. Atlas is Hemisphere’s industry-leading global correction service, which can be added as a subscription to C631. Atlas provides centimeter-level correction data worldwide via L-band communication satellites. With Atlas, C631 users can achieve sub-decimeter positioning performance anywhere on the planet without having to be near GNSS or communications infrastructure.
