Hemisphere GNSS Launches New Survey Smart Antenna

Hemisphere GNSS has debut S321, a next-generation multi-frequency, multi-GNSS survey smart antenna.

The all-new S321 combines Hemisphere’s Athena and Atlas technologies along with a completely new web UI offering an unparalleled level of customer-friendly performance, making it applicable to any land or marine survey portfolio.

“The S321 is another example of how much Hemisphere has changed,” says Chuck Joseph, Hemisphere’s president and CEO. “A fantastic survey smart antenna with industry-leading RTK, connectivity, and management capabilities, the S321 offers unbeatable performance and value to the industry.”

Key features of the S321 include:

  • Athena RTK engine
  • GPS, GLONASS, BeiDou, Galileo, QZSS
  • 372 channels
  • Atlas corrections delivered via L-band and over the Internet
  • Wireless connectivity via Bluetooth and Wi-Fi
  • Powerful web UI
  • Two versions :UHF + GSM/WCDMA and GSM/WCDMA (Network Rover)
  • 4 GB internal memory card and 64 GB-capable MicroSD card for data logging, download and upload

The antenna is designed to offer a wide range of functionality and ease of use, making it especially relevant to marine construction, hydrographic surveying, or dredging. Using the S321 with Athena RTK helps surveyors maintain peak up-time, maximizing return on investment. The ruggedized antenna was designed for the most demanding and challenging environments and meets IP67 requirements.

Athena RTK is designed to excel in virtually every environment where high-accuracy GNSS receivers can be used. Hemisphere’s customers have tested and proven Athena’s performance in long-baseline, in open-sky environments, under heavy canopy, and in locations experiencing significant scintillation.

The S321 ships preconfigured to test-drive corrections from Hemisphere’s recently-announced Atlas global corrections service. The bundled solution provides users worldwide with a simplified way to utilize Atlas, including their worldwide H10 service, offering 8-centimeter, 95-percent accuracy.

BaseLink technology allows Atlas-capable receivers like the S321 to self-calibrate, self-survey, and automatically manage the transmission of RTK correction data to augment or extend established or new GNSS reference networks in areas of poor Internet connectivity.

The S321 introduces Hemisphere’s all-new aRTK technology. Powered by Atlas, aRTK enables the S321 to operate with RTK accuracies when RTK corrections fail. If the S321 is Atlas-subscribed, it will continue to operate at the subscribed service level until RTK is restored.

The antenna also introduces SureFix, Hemisphere’s new processor running in combination with Athena to provide high-fidelity, RTK-quality information that results in precision with a high level of reliability.
