The SBG Systems new Quanta UAV series is a line of inertial navigation systems (INS) dedicated to UAV-based surveying integrators.

Because SBG Systems wants UAV surveyors to save autonomy for additional survey lines, the company has designed a small, lightweight, and low-power INS offered on two levels of accuracy. Quanta UAV and Quanta UAV Extra have been developed for compact LiDAR to high-end BVLOS mapping solutions. They provide precise orientation and centimeter-level position data delivered both in real time and post processing. This direct geo-referencing solution eliminates the need for ground control points and greatly reduces the need of overlapping.

Qinertia, SBG’s post-processing software completes the Quanta UAV offer. It gives access to offline real-time kinematic (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. This advanced software also computes the base station position to quickly provide centimeter accuracy. Qinertia comes free for one year with the Quanta UAV sensor.

Quanta UAV embeds high quality gyroscopes and accelerometers factory calibrated from -40 to +85°C. It also integrates an RTK GNSS receiver providing a centimetric position. The internal Extended Kalman Filter fuses inertial and GNSS data for the highest performance in the most challenging conditions.
