In Ukraine, there are the first drones on solar batteries. They are able to scan up to 20 thousand hectares of agricultural land in one working day and make autonomous flights lasting 6-8 hours. This indicator has a prospect to increase.
They take off using a catapult or from the hands of an operator of an unmanned aerial vehicle, the site of the developer Drone.ua reports.
The device recognizes and classifies weeds, monitors the development of biomass, predicts yields, recognizes and predetermines the appearance of pests, diseases, soil erosion, etc.
Such monitoring will help to increase the productivity of agricultural products by approximately 30%, as well as reduce the costs of fertilizer and protective equipment.
Solar-powered drones use the Solar 3 platform, which is manufactured at the Swiss Federal Institute of Technology ETH Zurich. The Gamaya camera and cloud data processing products act as the platform sensor and analytics systems. The activity of electromagnetic reflection fixes the hyperspectral sensor in 80 channels in the wavelength range 400-100 nanometers, instead of the classical 3-4 channels of multispectral cameras. This helps to more accurately remotely determine the biophysical and physicochemical properties of plants and soil.
This is the result of an international project, Swiss and Ukrainian companies, with the financing of the International Space Agency.
In the world, such technologies are used by Google and Facebook.
