Geavis uses senseFly eBee unmanned aerial vehicle whose flight endurance with a full battery is for about 45 minutes, and during that time it can overfly 30 km. By replacing the batteries, the time in service can be prolonged and the aerial photographing can cover an area to 10 km2. The flight endurance is reduced by the wind, frequent changes in the height levels or very low temperatures. The travel speed of the aerial vehicle is typically 36-57 km/h (10-16 m/s), while the take-up rate is approximately 3 m/s. To perform the intended flight, the aerial vehicle needs only locally favourable weather conditions in the area of taking the aerial photographs: cloud base of 300 m above the ground level and absence of stronger winds. Maximum wind speed which still allows the aerial vehicle to fly is 45 km/h (12 m/s). During such a wind it is guaranteed that the aerial vehicle can be returned to its take-off place when the sensors of aerial vehicle detect stronger winds.
