Fotokite is an autonomous tethered UAS designed to provide mission-critical situational awareness for public safety and first responders. As an ETH Zurich spinoff supported by a European Horizon 2020 technology grant, the platform delivers uninterrupted, high-resolution thermal and video telemetry, overcoming the flight-time limits and piloting demands of traditional drones. Its active tether to a vehicle-mounted base station enables fully autonomous, indefinite operation without a dedicated pilot, allowing teams to focus solely on the mission. Engineered for fire and rescue services, Fotokite is authorized by aviation authorities, offering teams a safer, more reliable alternative to free-flying drones. With single-button launch, flight, and landing, it maximizes safety, efficiency, and operational uptime for emergency response teams.
