The new multi-GNSS S321+ and C321+ GNSS smart antennas from Hemisphere GNSS are upgrades to the previous S321 and C321.

“The S321+ and C321+ represent the advanced technology, durability and ease of use that our customers have come to expect,” says Miles Ware, director of marketing at Hemisphere GNSS. “By upgrading these systems with increased functionality and management capabilities, we are offering unbeatable value to the industry.”

The smart antennas, powered by Eclipse P326 OEM board, support 394 channels. They can simultaneously track all satellite signals including GPS, GLONASS, BeiDou, Galileo and QZSS. The new S321+ and C321+ come standard with two long-life lithium batteries, providing up to 12 hours of operation. The batteries are hot-swappable so users can change them without having to stop working.

The S321+ and C321+ combine Hemisphere’s Athena GNSS engine and Atlas L-band correction technologies with a new webUI. The ruggedized antennas are designed for challenging environments and both meet IP67-standard requirements. The S321+ and C321+ come in two versions, with 4G LTE optimized for either North American or international locations.

The smart antennas provide centimeter-level RTK. Athena’s performance has been tested and proven with long baselines, in open-sky environments, under heavy canopy and in geographic locations experiencing significant scintillation.

The S321+ and C321+ ship pre-configured to test-drive corrections from Hemisphere’s Atlas L-band correction service. The bundled solution provides users worldwide with an easy way to utilize Atlas, including Hemisphere’s Atlas H10 service offering 8-centimeter, 95-percent accuracy (4 centimeters RMS). They also use Hemisphere’s aRTK technology, powered by Atlas, which allows the receivers to operate with RTK accuracies when RTK corrections fail. If the S321+ and C321+ are Atlas-subscribed, they will continue to operate at the subscribed service level until RTK is restored.

The S321+ is intended for use in applications such as land and marine surveying, 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 percent reliability.

The C321+ was designed specifically for construction environments, adding another system component that empowers heavy equipment manufacturers to deliver their own machine control and guidance solutions to their customers. The C321+ can also be paired with Hemisphere’s recently-announced SiteMetrix site management software platform that helps manage construction jobsite activities, including grade and volume checking.
