Hemisphere S631 Multi-Frequency, Multi-GNSS Smart Antenna
The S631 is a multi-GNSS, multi-frequency smart antenna from Hemisphere. It provides robust performance and high precision in a compact and rugged package. With multiple wireless communication ports and an open GNSS interface, the S631 can be used in a variety of operating modes. Use the S631 as a precise base station sending RTK to your existing rover network. Turn S631 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 receiver status and operation, as well as to upgrade the S631 with new firmware and activations. S631 is Athena™-enabled and Atlas®-capable (subscription required).
The S631 receiver is powered by Athena™ RTK technology. With Athena™, S631 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 S631 allows for RTK corrections to be received over radio, cell modem, Wi-Fi, Bluetooth, or serial connection. S631 delivers centimeter-level accuracy with virtually instantaneous initialization times and cutting-edge robustness in challenging environments.
The S631 receiver also enables users to work with Atlas®. Atlas® is Hemisphere’s global correction service, which can be added as a subscription to the S631. Atlas® delivers world-wide centimeter-level correction data over L-band communication satellites. With Atlas®, S631 users are able to experience sub-decimeter positioning performance anywhere on earth, without the need to be near a GNSS or communication infrastructure.
