Marine construction and dredging
Some of the largest dredging companies in the world are using Septentrio GNSS receivers. High accuracy at sea can be achieved with a PPP sub-decimeter accuracy service, via L-band satellite reception. Our receivers offer dedicated L-band demodulator and a separate L-band input for the most robust and reliable PPP service. Transmitting equipment aboard the ship such as antennas and radios can interfere with GNSS signals. To combat this, our marine receivers offer AIM+ Advanced Interference Mitigation technology, with an enhanced Iridium and Inmarsat uplink interference protection.

Marine mapping
RTK positioning provides geodetic-level positioning accuracy for bathymetry, marine survey and mapping. Centimeter-level positioning can be achieved in real-time when operating near-shore or during the post-processing stage. Septentrio offers Post Processing Software Development Kit (SDK) for efficient and easy post-processing of logged positioning data.
Autonomous ships
Transport barges are more energy efficient and safer than their rail or road counterparts. With automation fuel costs, rout efficiency and cargo space can be further optimized. For reliable autonomous navigation Septentrio RAIM+ integrity algorithms provide honest error information (uncertainty limits) about the positioning output. This mechanism ensures that only highly accurate positioning is used for autonomous navigation. Dual antenna receivers are available to provide heading information in addition to robust positioning. APME+ proprietary algorithm ensures high accuracy in in tight spots like a lock, where reflected GNSS signals can cause multipath.
