SBG Systems’ inertial navigation systems are ultra-high precision sensors combining inertial measurements and GNSS position measurements for efficient navigation. The attitude measurements are suited for all types of applications for marine, underwater, land or air vehicles.
Each SBG Systems inertial navigation system series is composed of several versions, with or without an internal RTK GNSS compass. When equipped with the compass, these so-called inertial navigation systems update the RTK GNSS position and heading in case of loss of GNSS signals for a short period of time (e.g. travel under a bridge, at the base of a quay or a large infrastructure).
Roll and pitch measurements are calculated using high-end MEMS technology, with an accuracy to one tenth and one hundredth of a degree. SBG Systems inertial navigation systems can be combined with various positioning and remote sensing technologies (GNSS receiver, Lidar, single or multibeam echosounder, sonar, etc.), and used on a wide variety of systems (USVs, ROVs, autonomous vehicles, hydrographic vessels, etc.). The Navsight Subsea series is a waterproof version for hydrographic operations.
Qinertia is a new generation of post-processing software combining computing power with a simple and practical interface for ease of use. Data from the SBG inertial navigation systems and GNSS receivers are processed in a tightly coupled system with access to over 7,000 reference stations worldwide. Qinertia improves navigation data, provides access to more in-depth analysis and fills in trajectory data-gaps due to complex environments (long tunnels, urban canyons, etc.).
Our philosophy is to support our clients at all key stages of their projects.
