Shom, the French national hydrographic and oceanographic office selected SBG Systems’ inertial navigation sytems to renew their whole fleet of INS. They chose the cost-effective and easyto- use Navsight Apogee INS for their speedboats and survey vessels for both shallow and deepwater real-time bathymetric surveys and Qinertia PPK software for post-processing tasks.
Shom, the French national hydrographic and oceanographic office
Shom, as a public institution, has 3 major objectives: national hydrography and cartography, defense support in hydrooceanographic fields, and support in maritime geospatial products and services for public policies on the sea and the coast. The fleet used by Shom is based in Brest and is composed of eleven boats, including seven speedboats, and three 59-meter long BH2 survey vessels. They operate on shallow and deep water in France, Africa, the Indian Ocean and in the Caribbean Sea. Shom also uses a fleet based in New Caledonia composed of two boats, one speedboat and a buoy-laying Vessel used part of the time for hydrographic surveys.
Renewing the fleet of Inertial Navigation Systems with SBG
When it came to renewing the fleet of inertial navigation systems (INS), the Shom looked at INS complying with IHO standards for bathymetric surveys, with a focus on roll and heave that have the biggest impact on the multibeam echo sounder data compensation.
After having conducted several tests in their official test zone where each element’s location is strictly and precisely known, Shom selected SBG Systems for the replacement of inertial navigation systems. If at first, they acquired a Navsight Ekinox grade (0.02° roll) for shallow water survey in New Caledonia, they then decided to move the fleet in Brest with Apogee grade INS solutions (0.008° roll). “The Apogee is highly versatile; it fits both deep and shallow water requirements. Having a homogenized fleet of sensors for speedboats and BH2 is easier to maintain, like the number of spare equipment, for example,” explains Rémi Labonde, in charge of Positioning and Hydrographic Equipment at Shom. Designed for hydrographers, Navsight Apogee grade is composed of a GNSS receiver and a processing unit enabling the real-time fusion of inertial and navigation data. Navsight provides connections to several external equipment such as echo sounders, computers, etc. With its titanium enclosure, the Apogee sensor could be installed in the floodable engine compartment, close to the multibeam echo sounder.
Navsight Apogee INS: Choosing Simplicity and Best Price/Performance Ratio
Navsight Apogee solution is a high performance cost-effective inertial navigation system based on state-ofthe- art MEMS technology; it, therefore, requires no annual maintenance. The SBG solution includes free unlimited firmware updates and technical support. “We have selected SBG for the good performance/price ratio and the high level of service. The SBG technical support team is available, reactive, and committed,” adds the Shom professional. Another key factor when choosing the INS solution was the ease of use. Once connected through Ethernet, the Navsight inner web interface guides the user during the installation phase. For example, a 3D view of the boat shows the entered parameters so that the user can check the installation in realtime. The embedded filter also controls and validates lever arms and antenna alignment during this procedure, which can be a plus if the Shom needs to calibrate a new system abroad. “We are big fans of SBG’s web interface. It is modern, extremely clear, and easy to use; it really makes a difference in our team’s work,” to conclude Rémi Labonde.
Saving the Day with Qinertia Post-processing Software
Navsight Apogee INS accepts real-time corrections from Real Time Kinematic (RTK) or Precise Point Positioning (PPP). In their daily surveys, the Shom uses PPP positioning for its big advantage of not requiring any installation compared to RTK. It also allows surveying offshore, or even near shore when no RTK correction is available. If most of their data is collected in real-time, Shom hydrographers employ SBG Systems’ in-house post-processing software called Qinertia to understand and fix data issues due to communication cuts. At the end of the day, the onboard team checks the data and corrects them with Qinertia if needed. The PPK software is known to be intuitive and Rémi Labonde confirms this: “It’s nice to have a software that is clear and easyto- handle.” www.sbg-systems.com

Vibrations during the construction of a new 1,890-meter tunnel adjacent to Casablanca’s Old Medina, the 250-yearold section of the famed Moroccan city, challenged the stability of its historically important buildings.
To monitor in real time the effects on the Medina’s aging buildings and to confirm that the construction work meets all engineering standards and guidelines, ETAFAT, a geospatial information acquisition and processing company, used the Nikon XF Total Station to perform more than 100 daily inspections. The ETAFAT team relied on optical targets placed on building facades whose coordinates were determined by forced centering to complete the inspections.
The Nikon XF 1” with its fast autofocus function, saved considerable field time. It enabled very fast collection of highly accurate observations throughout the monitoring and control of the planimetric and altimetric locations of the structure. The monitoring of the buildings during the various phases of the tunnel’s construction generated a large amount of data essential for understanding the consequences of the work and defining any necessary corrective measures. www.trimble.com
Teledyne CARIS’ HIPS and SIPS 11.3 release
Teledyne CARIS released HIPS and SIPSTM 11.3. This new software upgrade will introduce the first-ever COTS (commercial-off-the-shelf) release of an AI solution for classifying and cleaning sonar noise. Teledyne CARIS seeks to reduce significantly the need for manual cleaning and to move data swiftly from acquisition to review. The Sonar Noise Classifier automatically identifies the vast majority of sonar noise, resulting in a reduction of manual cleaning effort by a factor of up to 10x at an accuracy of 95%. This allows the hydrographer to focus more time on other important aspects of the survey and processing workflow. teledyne.com

An experimental navigation satellite being developed by L3Harris for the U.S. Air Force has passed a preliminary design review, clearing the way for the program to move forward. The Navigation Technology Satellite-3 (NTS-3) is an experiment to show that a layer of smaller satellites in geosynchronous Earth orbit could be deployed to supplement the medium Earth orbiting GPS constellation and improve the resiliency of the military’s positioning, navigation and timing capabilities. The Air Force Research Laboratory plans to launch NTS-3 in 2022.
NTS-3 also will be used to develop technologies such as experimental antennas, flexible and secure signals, automation and use of commercial command and control systems. If successful, these technologies would transition to the GPS 3F satellites made by Lockheed Martin, the Air Force said. In September 2018, the Air Force awarded Lockheed Martin a contract for up to 22 GPS 3F satellites. L3Harris in January 2019 received a $243 million award to provide the navigation signals for the first two GPS 3F spacecraft. https://spacenews.com
