SBG Systems offers GNSS+inertial navigation for surveying, UAVs

October 11, 2018  - By

SBG Systems is launching the Navsight Land & Air Solution, high-performance inertial navigation designed to make surveyors’ mobile data collection easier, whether for mobile mapping, GIS or road inspection.

SBG Systems will release the Navsight Land & Air Solution at the Intergeo show in Frankfurt, Germany, Oct. 16-18.

The solution consists of an inertial measurement unit (IMU), available at two different performance levels, connected to Navsight, a rugged processing unit embedding fusion intelligence and a GNSS receiver. It also has connections for external equipment such as lidar, cameras or computer.

The Navsight Land & Air Solution is the result of more than 10 years of experience in the mobile positioning industry, especially in the unmanned industry where position reliability is mandatory. SBG’s fusion algorithms allow the company to get the best performance from inertial, odometer and GNSS technologies; exclude false GNSS fixes; and improve the trajectory in complicated areas such as urban canyons, forests and tunnels.

According to the company, the Navsight Land & Air Solution supports all GNSS constellations, real-time kinematic (RTK) and precise point positioning services such as Omnistar and TerraStar.

SBG IMUs are easy to install, the company said. The sensor alignment and lever arms are automatically estimated and validated. Once connected to the Navsight processing unit, the web interface guides the user to configure the solution. A 3D view of the vehicle shows the entered parameters so that the user can check the installation. By choosing the vehicle, such as a plane or a car, the inner algorithms are automatically adjusted to the application. The Navsight unit also integrates LED indicators for satellite availability, RTK corrections and power.

INS/GNSS Post-Processing Software. Qinertia, the SBG post-processing software, provides access to offline RTK corrections from more than 7,000 base stations in 164 countries. Trajectory and orientation are greatly improved by processing inertial data and raw GNSS observables in forward and backward directions.
