AsteRx-U3 Marine

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.

Full-constellation, triple-frequency satellite tracking on both antennas
Sub-degree GNSS heading & pitch or headingand roll
Centimetre-level (RTK) and sub decimetre-level (PPP) position accuracy
L-band reception, robust against Iridium andInmarsat uplink interference
Support for FUGRO Marinestar corrections
Septentrio GNSS+ algorithms for reliableperformance
Integrated UHF radio, cellular modem,Bluetooth and Wi-Fi
