Introduction
Overview and Features
The S321+ is an 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
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 (WebUI) is used to control, manage, and upgrade the
S321+ with new firmware and activations. S321+ is Athena-enabled and Atlas-capable.
Powered by the Eclipse™ P326 OEM board, the S321+ supports 394 channels and can
simultaneously track all satellite signals including GPS, GLONASS, BeiDou, Galileo, and QZSS,
making them robust and reliable. S321+ comes standard with two long-life lithium batteries
providing up to 12 hours of operation. The batteries are hot-swappable, and may be changed
while working, maximizing your efficiency and ROI.
The S321+ combines Hemisphere’s Athena GNSS engine and Atlas L-band correction
technologies with a new WebUI, offering an unparalleled level of customer-friendly performance.
The ruggedized antenna is designed for the most challenging environments and meets IP67-
standard requirements. The S321+ comes in two versions, with 4G LTE optimized for either North
American or international locations.
Powered by Athena GNSS engine, the S321+ provides best-in-class, centimeter-level RTK.
Athena excels in virtually every environment where high-accuracy GNSS receivers can be used.
Tested and proven, Athena’s performance with long baselines, in open-sky environments, under
heavy canopy, and in geographic locations experiencing significant scintillation is nothing short of
cutting edge.
The S321+ is the ideal positioning system for use in applications such as land or marine survey, GIS,
mapping, and construction. Together with SureFix™, Hemisphere’s advanced processor, the S321+
delivers high-fidelity RTK quality information that results in guaranteed precision with virtually 100%
reliability.
S321+ User Guide Chapter 1 - Introduction Page 3 of 73
Athena RTK
The S321+ receiver is powered by the 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 instantaneously initialization times and cutting-edge
robustness in challenging environments.
Athena RTK (Real Time Kinematic) technology is available on Eclipse‐based GNSS receivers.
Athena RTK requires the use of two separate receivers: a stationary base station that broadcasts
corrections over a wireless link to the rover. The localized corrections are processed on the rover
to achieve superior accuracy and repeatability. Performance testing has shown exceptional
positioning accuracy even in harsh environments.
Athena RTK has the following benefits:
Improved Initialization time ‐ Performing initializations in less than 15 seconds at better
than 99.9% of the time
Robustness in difficult operating environments ‐ Extremely high productivity under
the most aggressive of geographic and landscape oriented environments
Performance on long baselines ‐ Industry‐leading position stability for long baseline
applications
S321+ User Guide Chapter 1 - Introduction Page 4 of 73
Atlas L‐band
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 near a GNSS or communication infrastructure.
With Atlas, the positioning accuracy does not degrade as a function of distance to a base station,
as the data content is not composed of a single base station’s information, but an entire network’s
information.
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
The S321+ is supported by our easy‐to‐use Atlas Portal (www.atlasgnss.com), which empowers
you to update firmware and enable functionality, including Atlas subscriptions for accuracies from
meter to sub‐decimeter levels.
For more information about Athena RTK, see:https://hemispheregnss.com/Technology For more
information about Atlas L‐band, see: https://hemispheregnss.com/atlas
If your S321+ is equipped with a 400 MHz radio, you may be required to obtain
a valid radio license for your jurisdiction.
aRTK Position Aiding
aRTK is an innovative feature available in Hemisphere’s S321+ smart antenna that greatly
mitigates the impact of land‐based communication instability. Powered by Hemisphere’s Atlas L‐
band system service, aRTK provides an additional layer of communication redundancy to RTK
users, assuring that productivity is not impacted by intermittent data connectivity.
S321+ receives the aRTK augmentation correction data over satellite, while also receiving the
land‐ based RTK correction data. With this, the receiver internally operates with two sources of
RTK correction, creating one additional layer of correction redundancy as compared to typical
RTK systems. Once that process is established (which takes as less than a few seconds), the
receiver is able to operate in the absence of either correction source, or in other words, the
receiver is able to continue generating RTK positions in case the land‐based RTK correction
source becomes unavailable for a period of time.
S321+ User Guide Chapter 1 - Introduction Page 5 of 73
SureFix™ RTK Position
To provide high fidelity quality indicators to the users, Hemisphere created an additional
processor that runs in combination with the RTK engine, called the SureFix™ processor. The
SureFix™ processor takes several inputs, such as GNSS data, data preprocessing results, and
generated RTK solutions. The SureFix™ processor takes all available information and, by using
functional and stochastic analysis methods, determines the quality of the current RTK engine
solution. These are shown as “SureFix™ quality indicators”. The SureFix™ indicators are then
combined with the RTK solution before being provided to the user. At the end of the process, the
user has access to high fidelity information about the quality of the RTK solution.
What’s Included
As per Table 1.1 below, the S321+ is available in a variety of kits, with supplementary products
sold as “controller/option kits”, “accessory kits” or simply as separate accessories. Contents can
change without prior notice. Check the official price list to confirm contents.
Important: Charge your Li-on battery upon receipt of shipment. According to the 2017 IATA
Dangerous Goods Regulations and supplemental IATA Lithium Battery Guidance, batteries must
