Hemisphere GNSS Announces Next-Generation S621 GNSS Survey Smart Antenna

At last week’s INTERGEO expo and conference in Stuttgart, Germany and the ION GNSS+ conference in Miami, Florida, Hemisphere GNSS announced its next-generation multi-frequency, multi-GNSS S621 GNSS survey smart antenna. The all-new S621 is a complete redesign of the previous generation version (S321+) and offers added benefits and value to an already impressive range of features and functionality, according to the manufacturer.

Powered by the all-new Phantom™ 40 GNSS OEM board, the S621 survey smart antenna processes and supports more than 800 channels with flexible and scalable simultaneous tracking of every modern and planned GNSS constellation and signal including GPS, GLONASS, BeiDou (including Phase 3), Galileo, QZSS, NavIC (IRNSS), SBAS, and Atlas L-band. The Phantom 40 GNSS OEM board is powered by Hemisphere’s recently announced next-generation Lyra II digital ASIC, Aquila wideband RF ASIC, and Cygnus interference mitigation technology.

The S621 comes standard with two long-life lithium batteries supplying more than 12 hours of operation. The batteries are hot-swappable so you can change them without stopping work, maximizing your efficiency and ROI.

The S621 combines Hemisphere’s Athena GNSS engine and Atlas L-band correction technologies with a new WebUI, offering an unparalleled level of customer-friendly performance. UHF (400 MHz and 900 MHz) radio, cellular, Bluetooth, and Wi-Fi are said to make wireless communications and connectivity easy to use. The compact and ruggedized antenna is designed for the most challenging environments and meets IP67 requirements. The S621 also introduces an all-new IMU-based sensor fusion platform to support enhanced tilted pole measurements for land survey applications. This new design is immune to magnetic interference and is extremely reliable in virtually any environment.

“The S621 represents the advanced technology, durability, and ease-of-use that our customers have come to expect,” said Miles Ware, director of marketing at Hemisphere.

The S621 is the ideal positioning system for use in applications such as land or marine survey, GIS, mapping, construction, or any application that requires high-performance precision and positioning. With multiple operating modes, the S621 can be used as a precise base station sending RTK corrections to your rover network or turned into a lightweight, compact, and easy-to-use rover by connecting it to your base via UHF radio or to a cellular network. When used in base station mode, the S621 offers unprecedented access to additional BeiDou phase 3 satellites within your rover RTK solution.
