Navisys GR-U01 Industrial Grade USB GNSS Receiver (U-blox M10 "10th Generation" GNSS Chip, 1.5m Accuracy, 18Hz Update Rate, Ultra-low Power Consumption, IPX7 Waterproof, Fully EMI Shielded, Operating Temperatures from -40°C to +85°C)

The NaviSys GR-U01 is an industrial-grade GNSS receiver built on u-blox’s M10 Base GNSS engine, featuring ultra-low power consumption at just 16 mA without compromising its 1.5-meter accuracy.

The GR-U01 supports concurrent tracking of all four L1 GNSS constellations: GPS, GLONASS, Galileo, and BEIDOU, with an impressive update rate of up to 18 Hz.

It excels with advanced features such as anti-jamming and RF interference detection, as well as spoofing detection and reporting, ensuring reliable and secure positioning in challenging environments.

Despite its advanced capabilities, the GR-U01 maintains a compact form factor, with dimensions of 40 x 45 x 16 mm. The receiver is an industrial and commercial grade GNSS receiver with IPX7 waterproof, fully EMI shielded, and operates within a wide temperature range from -40°C to +85°C.

u-blox "U-Center 2" Tool

The GR-U01 utilizes the u-blox M10 chip, ensuring full compatibility with the latest u-center 2 software for fast and efficient GNSS receiver configuration in key applications. u-blox offers comprehensive user and developer documentation to support easy evaluation and streamlined development.

The U-center 2 software is specifically designed for u-blox M10 and F10 products. It is available for free download from the u-blox website, and we have also provided a copy below for your convenience.

Navisys "NaviViewerUx" Tool

In addition to the comprehensive U-Center 2 tool, the manufacturer Navisys also provides a convenient tool for easy configuration and diagnostics of the GR-U01 GNSS receiver.

GM-U01 Module

If you only need the module rather than a complete industrial-grade GNSS receiver, consider the GM-U01, which is the module version of the GR-U01 GNSS receiver.
