Drones
WingtraOne
This is a drone of the VTOL category, i.e. a drone with vertical take-off and landing. Thanks to this feature, we only need a 2×2 meter takeoff and landing area. In the air, on the other hand, it flips 90° and continues as a classic aircraft. The lift of the wings then allows us to fly faster and, most importantly, to save a lot of energy – longer flights than with quadcopters and other similar machines.

Wingtra UAV usage
The use of this VTOL aircraft is then mainly for large areas. Compared to a classic multicopter, we have a chance to get up to 12 times the area flown on one set of batteries. In case of using RX1R II camera and flight altitude of 100 meters we are able to cover 110 hectares of area with one flight.
The data collected in this way is further assembled to produce either an orthophoto image or a 3D model composed of a point cloud or mesh texture.
This kind of data is excellent especially in resolution and accuracy of the image.

PPK
We can use PPK technology to refine the material we have obtained. This involves refining the GPS coordinates down to 1 cm horizontally and 3 cm vertically.
This refinement always takes place after all the necessary data images have been acquired and therefore no further preparation is needed when flying.
Payload
RGB cameras – Mainly used for classic imagery and 3D terrain modeling. In our set there is a camera for large area objects for orthophoto images and another camera adapted for capturing objects to create 3D models.
Multispectral camera – We use it mainly in forestry. The advantage of this camera is the possibility of capturing additional spectra beyond R, G and B.

Photogrammetry and 3D models
Using laser scanning (Lidar), or RGB imaging (resolution up to 100Mpx) complemented by accurate GPS, we create very accurate 2D, 3D models of surfaces and objects.
