Description
The S321 is Hemisphere’s all-new multi-GNSS, multi-frequency, smart antenna. The S321 provides a robust performance and high precision in a compact and rugged package. With multiple wireless communications ports and an open GNSS interface, the S321 can be used in a variety of operating modes. Use the S321 as a precise base station sending RTK to your existing rover network. Turn S321 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 can be used to control and manage the receiver status and operation, as well as to upgrade the S321 with new firmware and activations. S321 is Athena-enabled and Atlas- capable.

Distinguishable features
The S321 receiver is powered by the Athena RTK (Real time kinematic) technology. With Athena, S321 provides state-of-art RTK performance when receiving corrections from a static base station or network RTK correction system. With multiple connectivity options, the S321 allows for RTK corrections to be received over radio, cell modem, Wi-Fi, Bluetooth, or serial connection. S321 delivers centimeter accuracy with virtually instantaneous initialization times and cutting edge robustness in challenging environments.
