With multiple wireless communication ports and an open GNSS interface, the C631 GNSS smart antenna from Hemsiphere can be used in a variety of operating modes. Use the C631 as a precise base station sending 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 Wi-Fi network. 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. C631 is Athena-enabled and Atlas-capable (subscription required).
The C631 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. With multiple connectivity options, the C631 allows for RTK corrections to be received over radio, cell modem, Wi-Fi, Bluetooth, or serial connection. C631 delivers centimeter-level accuracy with virtually instantaneous initialization times and cutting-edge robustness in challenging environments.
The C631 receiver also enables users to work with Atlas. Atlas is Hemisphere’s industry-leading global correction service, which can be added as a subscription to the C631. Atlas delivers world-wide centimeter-level correction data over L-band communication satellites. With Atlas, C631 users can experience sub-decimeter positioning performance anywhere on earth, without the need to be near a GNSS or communication infrastructure.
