S321+ GNSS Smart Antenna Surveyor Tough • Multi-Frequency, Multi-GNSS (GPS, GLONASS, BeiDou, Galileo, QZSS) • Athena™ RTK engine and Atlas® L-band global corrections • Dual hot-swappable lithium batteries provide 12 hours of battery life • Wi-Fi, UHF, Cellular, and Bluetooth wireless communication • Powerful WebUI control accessed via Wi-Fi • 8 GB internal memory for data logging, download, and upload 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.
