Hemisphere GNSS and Carlson Software have, together, produced the Hemisphere S321 and Carlson BRx6 compact, state-of-the-art GNSS receivers.

The two companies previously worked together on the design and production of Carlson's BRx5 GNSS receiver (Hemisphere S320), developed using Carlson's software and interface expertise with Hemisphere's design and manufacturing experience and RTK correction technology leadership.

“There are simply more satellite constellations available now, and more RTK correction services, and they can be used together to provide better accuracy and more efficient fieldwork,” says Carlson’s Director of Special Projects Karl Nicholas. “And even though receivers today are much lighter than they were just five years ago, our customers in surveying and construction tell us they want receivers that are even lighter and more compact, and sturdier, too.”

The new S321 and BRx6 receivers are optimized for land surveying, construction fieldwork and marine operations. Design and production focused on creating a lightweight and compact receiver with an intuitive interface and state-of-the-art access to multiple satellite constellations — including GPS, GLONASS, BeiDou and Galileo. The receivers also incorporate RTK and L-band corrections, including optimization for Hemisphere’s subscription-based Atlas GNSS Global Correction Service.

The new receiver is based on Athena, Hemisphere’s RTK engine, and is designed from the ground up to efficiently process multiple constellations and Atlas correction signals, resulting in both high-accuracy and robust performance. "Detailed testing performed by Carlson shows that Athena is a world-class RTK engine," Nicholas says. Together with Hemisphere’s BaseLink technology and a new webUI, the S321/BRx6 serves as a powerful rover or base station, even in locations where control points are not available.

“We were as motivated as Carlson to make this receiver excel as a base station,” says Hemisphere’s Senior Product Manager Lyle Geck. “BaseLink brings simplicity and freedom to setting up the S321 or BRx6 as a base station.” This expertise with RTK algorithms and L-band corrections was a primary reason Carlson sought out Hemisphere as a manufacturing partner.

Several features of the new receiver, including the new SureFix technology, were specifically designed to make surveyors more productive in the field or on construction sites. “In multi-path conditions, position reliability will often degrade,” Nicholas says. “Surveyors are aware of this, but it’s hard to compensate for when they don’t have information about what’s happening with accuracy. SureFix uses proprietary algorithms and various inputs to give a reliable, quality indicator for particular points.”
