UAV-based Survey
LiDAR and Photogrammetry
An Inertial Navigation System (INS) delivers motion and position information. It is used to synchronize and stabilize camera and LiDAR precisely while mounted onto the UAV.
It is also used for accurate data geo-referencing in real-time or at the office using the post-processing software.

Tips
One or Two Antennas for Accurate Heading?
A single antenna is good enough for accurate heading in high dynamics UAV applications while a 2 antenna GNSS receiver will provide a faster initialization as well as a more precise heading. When the UAV is in slow motion, dual antenna is highly recommended.
How to Obtain a Centimetric Position?
Several SBG sensors, such as the Ellipse2-D or the Ekinox2-D, integrate an RTK capable GNSS receiver. Performance can be greatly improved after the mission, using Qinertia, an SBG in-house Post-processing software.
Installation Tips
SBG sensors should be in a strap-down configuration. The antennas and the IMU should operate with fixed lever arms.
Why use a Post-processing Software?
Qinertia is the SBG PPK software. It uses inertial data and raw GNSS observables to provide a more precise attitude, heading, and position, thanks to a forward, backward, and merge processing. This operation is done at the office and only takes a few minutes.
