SBG Systems released the Navsight Marine Solution at the recent Oceanology International trade show in London. The solution consists of an Inertial Measurement Unit (IMU) available at two different performance levels (from shallow to deep water), and connected to Navsight, a rugged processing unit embedding the fusion intelligence, the GNSS receiver when selected, and all connections to external equipment such as echo-sounders, sonar, etc.
Navsight Marine Solution is based on 10 years of SBG Systems’ experience in marine inertial sensing products. The Ekinox and Apogee INS have been quite successful in the field; the company continues its efforts to offer even more performance, simplicity, robustness, and versatility to marine professionals.
Whether the IMU comes with a surface or a subsea enclosure, they are all lightweight and easy to install, according to the company. Navsight connects to any computer, with no software installation. Once connected through Ethernet, the web interface guides the user to configure the solution. A 3D view of the boat shows the entered parameters so that the user can check in real-time the installation. Navsight allows quick installation and initialization thanks to new mechanical calibration module. The embedded filtering controls and validates Lever arms and antenna alignment during this procedure.
Navsight Marine Solution is designed to provide high performance motion and navigation data as well as a real-time heave accurate to 5 centimeters, which automatically adjusts to the wave frequency. To allow surveying when wave frequencies are large or complex, Navsight comes with a delayed heave feature resulting in a heave accurate to up to 2 centimeters computed in real-time with a little delay. If higher performance is required, the surveyor can count on SBG INS/GNSS post-processing software named Qinertia. By processing inertial and GNSS raw data forward and backward, Qinertia greatly increases accuracy especially during GNSS outages; it also fixes set up mistakes, etc.
The versatile Navsight comes as a Motion Reference Unit (MRU), providing roll, pitch, and heave or as a full Navigation Solution with embedded tri-frequency GNSS receiver, or using an external one. Fusing inertial data with satellite position in real-time, Navsight INS offers a continuous position in all conditions, such as surveying under a bridge, or during GNSS outages due to coastal infrastructures (buildings, harbor cranes, etc.).
The Navsight Marine Solution supports real-time kinematic and every Precise Point Positioning service (Marinestar, TerraStar, etc.), according to SBG Systems. It is compatible with the main hydrographic software such as Hypack, QINSy, or Teledyne PDS for seamless integration into existing workflows.
Navsight is ITAR Free, and all models are available for order.
