Here at SPH Engineering we have a fleet of various drones we use for diverse research and development projects as well as testing new releases of UgCS.
When it comes to using drones for land surveying, mapping or 3D reconstructions, flight precision plays an important role. This is why we decided to test the precision of different drones to see how well they compare to one another. For that we prepared a short photogrammetry mission in UgCS to see how well does the actual flight trajectory correspond to survey lines.
In the first part we tested the DJI Phantom 4 using different turn types: first flight with Stop and Turn, second - Adaptive Bank. See the flight comparison in the video below:
We will try and publish one drone test per week. Next-up will be the DJI Naza-M V2.
