GNSS products launched on marine market

Belgian high-precision GNSS (Global Navigation Satellite System) firm Septentrio has launched two GNSS receivers for dredging, marine construction and offshore applications. 

AsteRx-U3 Marine and AsteRx-m3 Fg both offer accurate positioning via centimetre-level RTK (real-time kinetic) or a built-in Fugro PPP subdecimeter subscription service, which can be delivered over L-band satellite if internet is not available.

“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,” said Silviu Taujan, Product Manager.

”They are both feature-rich receivers, combining the best-in-class RTK base and rover functionality with an option of sub-decimeter PPP positioning.“ 

Marine projects are increasingly being threatened by jamming – when GPS frequency is overpowered by other radio waves – or ‘spoofing’, a malicious form of radio interference where misleading signals are sent into the receiver, resulting in faulty co-ordinates that lead the target away from its predefined track.

”Having robust GNSS technology means accurate and uninterrupted positioning on any vessel, even in challenging marine environments,” says the company.
