The S631 multi-GNSS smart antenna from Hemisphere delivers centimeter-level accuracy with cutting-edge robustness and virtually instantaneous initialization times even in challenging environments. It can be used in several operating modes via an open GNSS interface and multiple wireless communication ports.

Use the S631 as a lightweight rover by connecting it to your base via cellular network or UHF radio. Turn S631 into a precise base station sending RTK to your existing rover network. The built-in web user interface can be used to upgrade the S631 with new firmware and activations, as well as to monitor and control the receiver status and operation.

The S631 is Athena-enabled and Atlas-capable (subscription required). With Athena, S631 provides state-of-the-art RTK performance when receiving corrections from a network RTK correction system, or a static base station. With multiple connectivity options, the S631 allows for RTK corrections to be received via serial connection, Bluetooth, Wi-Fi, cell modem, or radio.

The S631 receiver also enables users to use Atlas. Atlas can be added as a subscription to the S6321 and it provides Hemisphere’s industry-leading global correction service. Atlas delivers global centimeter-level correction data over L-band communication satellites. S631 users are able to experience sub-decimeter positioning performance anywhere on earth with Atlas, without having to be near a communication or GNSS infrastructure.
