The S321+ GNSS smart antenna can be used in different operating modes, including as a base station sending RTK to an existing rover network, or as a lightweight rover by connecting it to a base with Wi-Fi or UHF radio. The receiver status and operation can be controlled and managed with the web user interface. The S321+ is also Atlas-capable and Athena-enabled.
Atlas, Hemisphere’s global correction service can be used by the S321+ receiver to deliver centimeter level world-wide correction data over L-band communication satellites.
By using Athena RTK technology, the S321+ provides state-of-art RTK performance when is receives corrections from a networked RTK correction system or static base station. The S321+ has multiple connectivity options enabling RTK corrections to be received via cell modem, radio, Bluetooth, Wi-Fi, or serial connection.
