SBG Systems releases Navsight inertial for marine surveys

SBG Systems has released the Navsight marine solution, a full high-performance inertial navigation solution designed to make surveyors’ tasks easier in both shallow and deep water.

Navsight consists of an inertial measurement unit available at two different performance levels (from shallow to deep water). According to SBG Systems, the Navsight marine solution is based on 10 years of the company’s experience in marine inertial sensing products.

Whether the IMU comes with a surface or a subsea enclosure, they are all lightweight and easy to install, the company said. 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 provides high-performance motion and navigation data as well as a real-time heave accurate to 5 cm, which automatically adjusts to the wave frequency, SBG Systems said.

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-cm 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.

Highly versatile, Navsight comes as a Motion Reference Unit, 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 continuous position in all conditions, such as surveying under a bridge, or during a GNSS outages due to coastal infrastructures (buildings, harbor cranes, etc.).

The Navsight Marine Solution supports RTK and every precise point positioning service (Marinestar, TerraStar, etc.). 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. All models are available for order. Ordering information and delivery time are available from SBG Systems representatives and authorized SBG Systems dealers.
