The S631 from Hemisphere is a Multi-Constellation GNSS Smart Antenna that supports GPS, GLONASS, BeiDou, Galileo, QZSS, IRNSS, and Atlas L-band constellations. It can receive long-range RTK baselines at a range of up to 50 km with a reacquisition time of 15 seconds. This antenna is Athena™-enabled and Atlas ®-capable and provides state-of-the-art RTK performance when receiving corrections from a static base station or network RTK correction system. It has an internal sensor that corrects collected point coordinates. With multiple connectivity options, the S631 allows for RTK corrections to be received over radio, cell modem, Wi-Fi, Bluetooth, or serial connection. This antenna delivers centimeter-level accuracy with virtually instantaneous initialization times and cutting-edge robustness in challenging environments.
The S631 supports Bluetooth 2.1+EDR/4.0 LE, Wi-Fi 802.11b/g, UHF (400 MHz & 900 MHz), LTE FDD/TDD, UMTS and GSM communication bands. It has an internal memory of 8 GB which is expandable via SD card up to 32 GB. The built-in web user interface (WebUI) can be used to monitor and control the receiver status and operation, as well as to upgrade the S631 with new firmware and activations. This antenna requires a DC supply of 9-28 V and can operate for up to 12 hours on removable dual batteries of 7.2 V, 3400 mAh each. It is available in a module that measures 156 x 76 mm and has TNC and LEMO (5/7 pin) connectors.
