With the new additional funding The contracting authorities intends to jointly buy two (2) more devices as follows: Aerial drone fleet with data loading and recharging docking station (unmanned aerial vehicle (UAV)) with the following mandatory minimum requirements: - with take-off weight less than 25 kg. Total weight not exceeding 25 kg, payload capacity more than 2 kg (payload must be interchangeable e.g., RGB, spectral cameras, lidar). Therefore, these kinds of instrumentations should be able to attach onto the drone. - the maximum weight of the offered docking station is 140 kg - Flight time with maximum payload should be at least 30 min - Minimum flight speed of the drone should be 3 m/s or less. Capability also to fly with up to 8 m/s or more. - Safety systems for landing (e.g. parachute) - System should be fully electric - Drone and its sensors should fit onto docking station - Operation wind conditions, up to 12 m/s wind speed - Size of the system: under 3 meters in diameter, transport less than size 2 m in diameter - A water proof (IP44 minimum, recommended IP55) drone and drone platform for outdoor use. - Minimum 4G connection with automatic data transfer to cloud service or similar. - Costs of the maintenance and maintenance program (done by user or company) should be specified. (user maintenance preferred) - Operating Temperature range at least -10 to 40C, - The drone should be equipped with a location positioning system (GNSS: GPS+GLONASS+BeiDou+Galileo). Options for RTK and VRS functions are required. - Battery swap and/or charge so that downtime maximum is 60 minutes. - radio control range up to 7 km from docking station - Applications: Remote control software. Cloud Platform support (EU based), can be own cloud or a support of 3rd Party Platforms through
