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

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 the most 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.

Powered by Athena GNSS engine, the S321+ and C321+ centimeter-level RTK. 

Atlas GNSS Global Corrections

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 cm 95% accuracy (4 cm 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 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.

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.
