Septentrio has launched two new GNSS* products for marine applications: AsteRx-U3 Marine and AsteRx-m3 Fg.

Both of these products offer accurate positioning near and offshore via centimeter-level RTK (Real-Time Kinematic) or the built-in Fugro PPP (Precise Point Positioning) sub-decimeter subscription service, delivered either over NTRIP (Networked Transport of RTCM** via Internet Protocol) internet or over L-band satellite. Corrections delivered over L-band allow dredging, bathymetry or marine construction projects even in areas where there is no internet service.

The AsteRx-U3 Marine receiver, enclosed in an IP68-rated housing, offers a unique feature of a dedicated L-Band demodulator with a separate L-Band RF input, which allows for the use of dedicated antennas for excellent reception of L-band signal even at high latitudes. Orders for both products can be placed immediately. Deliveries for AsteRx-m3 Fg will follow our standard lead times while deliveries for AsteRx-U3 Marine will start from July.

Septentrio GNSS technology is known for its resilience to RF interference which, on vessels, can come from satellite uplinks, such as Iridium modems or from other radio antennas. Marine jamming and spoofing*** are growing threats in certain areas of the world. Having robust GNSS technology means accurate and uninterrupted positioning on any vessel, even in challenging marine environments. Both AsteRx-U3 Marine and AsteRx-m3 Fg receivers offer accurate heading and pitch or heading and roll orientation information with the dual GNSS antenna configuration. For more information about the new marine receivers or other Septentrio products please contact the Septentrio team.

“The new products are designed around our most powerful GNSS core, bringing the latest evolution in GNSS technology to the demanding marine construction and dredging markets. They build on the success of the field-proven AsteRx-U Marine Fg and AsteRx4-Fg, with more processing power to allow tracking of all visible satellite signals while enabling higher update rates. AsteRx-U3 Marine and AsteRx-m3 Fg are both feature-rich receivers, combining the best-in-class RTK base and rover functionality with an option of sub-decimeter PPP positioning,“ said Silviu Taujan, Product Manager at Septentrio.

*Global Navigation Satellite System including the American GPS, European Galileo, Russian GLONASS, Chinese BeiDou, Japan’s QZSS and India’s NavIC. These satellite constellations broadcast positioning information to receivers which use it to calculate their absolute position.

***Jamming occurs when GPS frequency is overpowered by other radio waves. The result can be a loss of positioning accuracy or event total loss of position. Spoofing is a malicious form of radio interference, where misleading signals are sent into the receiver, resulting in faulty coordinates, which lead the target away from its predefined track.

Septentrio is an ISO 9001 certified manufacturer of multi-frequency multi-constellation GPS/GNSS positioning technology for demanding applications. Reliable centimeter-level positioning enables machine automation improving efficiency and safety. Septentrio provides positioning solutions for industrial applications such as robotics, construction, survey and mapping, maritime, logistics and unmanned aerial vehicles (UAVs). Septentrio has their headquarters in Leuven, Belgium, and has a world-wide presence with offices in Los Angeles, Shanghai, Seoul and Yokohama, as well as numerous partners around the world.
