AsteRx-U Marine Integrated GNSS Receiver

Product Information
Powered by the AsteRx4, the AsteRx-U MARINE is the most advanced multi-constellation dual receiver from Septentrio. Its multi-frequency engine can track all current and future Global Navigation Satellite System (GNSS) constellations – GPS, GLONASS, Galileo, BeiDou, NavIC and QZSS – on both antennas, guaranteeing reliable and accurate GNSS positioning now and into the future.
Septentrio’s knowledge and experience in the GNSS industry ensures that the ruggedised AsteRx-U MARINE offers you the highest possible accuracy, scalable to a centimetre. AsteRx-U Marine supports the Marinestar (Fg Model) PPP augmentation services.
Like the AsteRx-U, users can use any device to operate the AsteRx-U MARINE without any special configuration software via the built-in webserver accessible via WIFI, network or USB connection.
THE GNSS+ TOOLKIT – CONVERTING POOR ENVIRONMENTS INTO GOOD POSITIONING
Activity in the ionosphere is a problem for GNSS signals, from loss of RTK fix to total loss of signal lock. Septentrio has honed its skills by supporting applications in the most iono-active areas on Earth. The result is IONO+: the most advanced protection against ionospheric disturbances to GNSS signals on any receiver.
Metal and large nearby structures can reflect GNSS signals and produce multipath. The Advanced Multipath Mitigation Technology APME+ effectively disentangles direct and reflected signals enhancing both position and measurement quality. APME+ is bias free and can be disabled in line with Septentrio’s commitment to maximum configurability.
Advanced Receiver Autonomous Integrity Monitoring (RAIM+) comprises fault detection mechanisms of the receiver at all the levels including the generation of measurements, quality control and navigation algorithms. Detected faulty measurements, which are typically caused by high multipath or active ionosphere, are removed from the solution.
Mechanical vibrations or shocks caused by rough terrain can wreak havoc with satellite tracking. LOCK+ automatically adjusts the parameters of the AsteRx SB GPS / GNSS receiver so you never lose position.
AIM+ Anti-Jamming and RF Spectrum Monitoring System
The AsteRx-U Marine features AIM+, the most advanced onboard radio frequency interference (RFI) monitoring and mitigation technology on the market. It can suppress the widest variety of interferers, from simple continuous narrowband signals to the most complex wideband and pulsed jammers. The built-in protection against intentional and unintentional jamming and spoofing uses a sophisticated system of sampling and mitigation mechanisms. The RF spectrum can be viewed in real-time in both time and frequency domains.
The high-precision GPS reference receiver comes complete with 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 has easy-to-read quality indicators, ideal for monitoring the receiver operation during the job at hand.
