GNR5 GNSS Reference Receiver

The GNR-5 has a rugged, integrated design with longer operating times and high reliability. It is a GNSS reference receiver for many applications, including GNSS infrastructure network receivers, field (mobile) base stations, permanent reference stations, and reference stations for scientific analysis.

Leading Reference Station Receiver

Using Sokkia premium technologies the GNR5 GNSS receiver incorporates 452-channels capable of tracking multi-frequency signals from all GNSS constellations including GPS, GLONASS, SBAS, QZSS, Galileo and BeiDou. This comprehensive support includes current and modernized signals across the full GNSS spectrum, including multiple L-band signals. The optimized tracking has also demonstrated successful demodulation and tracking of advanced QZSS signal structures such as the LEX signal in E6.

The GNR5 receiver offers a complete connectivity solution by allowing the receiver to be accessed via Ethernet, Wi-Fi, or Bluetooth® as well as by using standard serial or USB ports. The GNR5 can also serve as a USB Host, providing a new web-based user interface that offers flexible configuration options and portability. The USB Host feature allows the user to connect a USB memory stick or USB Mass Storage Device (UMS) to the GNR5 receiver. The UMS provides a simple solution for transferring raw data files from the receiver’s SD card or extending the GNR5 with a semi-permanent high-capacity storage option. The GNR5 supports flash-based UMS devices as well as hard drive-based UMS devices.

Premium positioning technology, extended communication support, advanced web-server capability, longer operating time, and high-reliability make the Sokkia GNR5 the best selection for your reference network receiver.
