The NaviSys GR-U01U 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-U01U supports concurrent tracking of all four L1 GNSS constellations—GPS, GLONASS, Galileo, and BeiDou—with an update rate of up to 18 Hz. Advanced anti-jamming, RF interference detection, and spoofing detection/reporting help keep positioning reliable in challenging environments.

Despite its capability set, the GR-U01U stays compact at 40 × 45 × 16 mm. It is an industrial and commercial grade receiver with IPX7 waterproofing, full EMI shielding, and a wide operating range from −40°C to +85°C.

u-blox U-Center 2 Tool

The GR-U01U uses the u-blox M10 chip and is fully compatible with the latest u-center 2 software for fast GNSS receiver configuration. u-blox provides user and developer documentation to support evaluation and development.

U-center 2 is designed for u-blox M10 and F10 products. It is free from the u-blox website, and a copy is also available in the Product Resources section of this page.

Navisys NaviViewerUx Tool

In addition to U-Center 2, Navisys provides NaviViewerUx for convenient configuration and diagnostics of the GR-U01U GNSS receiver.

GM-U01U Module Option

If you only need the module rather than a complete industrial-grade GNSS receiver, consider the GM-U01U—the module version of the GR-U01U GNSS receiver.
