AsteRx-U3 is a multi-frequency, multi-constellation GNSS positioning and heading receiver, which includes a multitude of wired as well as wireless communications in a rugged IP68 housing, for the broadest range of applications.

Consistently accurate now and into the future

The AsteRx-U3 is the most advanced integrated multi-constellation dual-antenna receiver from Septentrio. Its multi-frequency engine can track signals from all Global Navigation Satellite System (GNSS) constellations: GPS, GLONASS, Galileo, BeiDou, NavIC and QZSS – on both antennas. This guarantees you reliable and accurate GNSS positioning now and into the future.

Reliable centimeter accuracy

Septentrio’s 20 years of experience in the GNSS industry ensures that the AsteRx-U3 offers the highest possible accuracy, down to the centimeter level. LOCK+ technology maintains tracking during heavy vibrations and IONO+ ensures position accuracy even during periods of elevated ionospheric activity. The AsteRx-U3 offers the very latest in advanced interference mitigation technology AIM+, which filters out ambient intentional and unintentional RF interference.

Any device, any platform

Use any device with a web browser to operate the AsteRx-U3 without any special configuration software via the Web interface, accessible over Ethernet, Wi-Fi or USB connections.

AIM+ anti-jamming and RF spectrum monitoring system

AIM+ offers built-in protection against intentional and unintentional jamming using a sophisticated system of sampling and mitigation mechanisms. Your high-precision GNSS receiver can automatically suppress the widest variety of interferers from simple continuous narrow-band signals to the more complex wide band and pulsed transmitters as well as lnmarsat and Iridium satellite transmissions.

Intuitive web user interface

With your high-precision GPS reference receiver comes an intuitive web user interface for easy operation and monitoring allowing you to control the receiver from any mobile device or computer. The web interface also uses easy-to-read quality indicators ideal to monitor the receiver operation during the job at hand.
