Hemisphere S321 GNSS SMART ANTENNA

The S321   (Plus) is a multi-GNSS, multi-frequency, smart antenna. It replaces the S321. The S321 provides robust performance and high precision in a compact and rugged package. It has multiple communication ports and an open GNSS interface, and can be used in a variety of operating modes. Use the S321 as a precise base station sending RTK to your existing rover network , or turn it  into a lightweight and easy to use rover by connecting it to a base via UHF radio or Wi-Fi . The built- in web user interface (web UI) can be used to control and manage the receiver status and operation, and to upgrade the S321 with new firmware and activations. The S321 is Athena-enabled and Atlas-capable.

Powered by Athena RTK technology. The S321 receiver is powered by the Athena RTK 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-level accuracy with virtually instantaneous initialization times and cutting edge robustness in challenging environments.

Works with ATLAS. The S321 receiver also enables users to work with the Atlas service. Atlas is Hemisphere’s industry leading global correction service, which can be added as a subscription to the S321 . The Atlas system delivers world-wide centimeter-level correction data over L-band communication satellites. With Atlas, S321 users are able to experience sub-decimeter positioning performance anywhere on earth, without the need to be nearby a GNSS or communication infrastructure.

Atlas L-band has the following benefits:

  • Positioning accuracy - Competitive positioning accuracies down to 2 cm RMS in certain applications.
  • Positioning sustainability - Advanced position quality maintenance in the absence of correction signals, using Hemisphere’s patented technology.
