The NaviSys GM-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 GM-U01 supports concurrent tracking of all five L1 GNSS constellations: GPS, GLONASS, Galileo, BEIDOU, and QZSS, with an impressive update rate of up to 18 Hz.
It excels with advanced features such as anti-jamming, RF interference detection, spoofing detection, and reporting, ensuring reliable and secure positioning in challenging environments.
This feature-rich GNSS smart antenna module not only minimizes design efforts but also enables the rapid deployment of AVL, timing, and other location-based applications. It supports various electrical interfaces, including USB, RS232, and UART TTL.
The power control feature allows convenient power on/off control via a GPIO pin, which is particularly useful for conserving power when the device is not in use.
Combining high performance and low power consumption in a compact form, the GM-U01 is suitable for a wide range of positioning, speed, and timing applications.
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.
