SURVEYING & INSPECTION Inertial Navigation Systems Full Test in


Hydrographic Applications with Interactive Maps SBG Systems put all its Inertial Navigation Systems to the test during a three-day hydrographic survey in the Hamburg port area, in Germany. Test results take the form of interactive maps so hydrographers can select a product and compare its performance through seafloor maps.

INERTIAL SENSORS PUT TO THE TEST


During the test, SBG Systems and their local partner McArtney GmbH have surveyed the Hamburg port area in Germany. They have tested three grades of their MEMS INS (Ellipse, Ekinox, Apogee) with their FOG Inertial Navigation Systems all coupled with a Multibeam Echosounder. SBG FOG-based INS named Horizon was post-processed within Qinertia PPK software to be used as a reference. The test was conducted in challenging conditions such as bridge crossing or dense urban areas, with the main focus being testing motion and position during GPS outages.


Elbbrücken 3D Model – general view


SBG Systems’ goal in this experiment was to provide professionals a guide to find out which sensor was best suited for a particular condition or situation. The test reports show how their inertial sensors perform in different scenarios encountered


during hydrographic surveys. The different versions of the results (web maps, 3D models…) allow to easily compare product performance.
