ABOUT
The S321+ is Hemisphere’s all-new multi-GNSS, multi-frequency smart antenna. The S321+ provides robust performance and high precision in a compact and rugged package. With multiple wireless communication 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 builtin web user interface (WebUI) 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 (subscription required).
The S321+ receiver is powered by Athena RTK technology. With Athena, S321+ 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 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.
The S321+ receiver also enables users to work with Atlas. Atlas is Hemisphere’s industry-leading global correction service, which can be added as a subscription to the S321+. Atlas 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 near 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.
