Product Information
Description
The Hemisphere GNSS C631 is the latest multi-frequency, multi-constellation GNSS smart antenna, delivering reliable performance and high positioning accuracy in a compact and rugged design. With multiple wireless communication interfaces and an open GNSS architecture, the C631 can be configured for a variety of surveying applications.
It can operate as a high-precision RTK base station, transmitting correction data to an existing rover network, or as a lightweight RTK rover, connecting to a base station via UHF radio or Wi-Fi.
The integrated WebUI allows users to monitor receiver status, configure settings, perform firmware upgrades, and manage feature activations. The C631 is Athena-enabled and supports Atlas correction services (subscription required).
Technology & Performance
Powered by Hemisphere's Athena RTK technology, the C631 delivers centimeter-level RTK positioning with near-instant initialization, even in challenging environments. It supports RTK corrections via UHF radio, cellular modem, Wi-Fi, Bluetooth, or serial communication, providing reliable high-precision positioning.
The C631 also supports the Atlas subscription service, delivering global L-band satellite corrections for sub-decimeter positioning accuracy anywhere in the world, without relying on a local GNSS base station or communication infrastructure.
