The AsteRx-U3 Marine is designed for marine survey  and construction users. It is a multi-frequency  GNSS receiver offering precise GNSS positioning  and heading with enhanced Iridium and Inmarsat  uplink interference mitigation.


KEY FEATURES

* Full-constellation, triple-frequency satellite tracking on both antennas 

* Sub-degree GNSS heading & pitch or heading & roll 

* Centimetre-level (RTK) and sub decimetre-level (PPP) position accuracy  

* L-band reception, robust against Iridium and  Inmarsat uplink interference 

* Support for FUGRO Marinestar corrections 

* Septentrio GNSS+ algorithms for reliable performance

* Integrated UHF radio, cellular modem, Bluetooth and Wi-Fi


BENEFITS

Consistently accurate now and into the future  

The AsteRx-U3 Marine 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.


Centimetre accuracy  

Septentrio’s 20 years of experience in the GNSS industry  ensures that the AsteRx-U3 Marine offers you the highest  possible accuracy, down to a centimetre. LOCK+ technology  maintains tracking during heavy vibration and IONO+  ensures position accuracy even under periods of elevated  ionospheric activity. The AsteRx-U3 Marine offers the very  latest in advanced interference mitigation technology AIM+,  which filters out ambient intentional and unintentional  RF interference and allows this receiver to be resilient to  interference from Iridium and Inmarsat uplinks. 


Any device, any platform 

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