EONEF designs and manufactures multi-service air platform autonomous in energy. It is a tethered helium balloon capable of flying for weeks. Our aerostats embed telecommunication and observation systems that are powered by ultralight solar panels. By rapidly gaining height, our technology enhances the coverage of the embedded equipment. EONEF provides you with weeks of flight in full autonomy: no energy source required, with minimum human interaction. Use cases: 1. Emergency & crisis (Secure a zone and enhance coordination in the area of operation) 2. Scientific missions (Observe wildlife in their natural environment, sustain air quality control) 3. Extensive & remote areas (Expand protection and avoid trespassing on wide industrial sites.)
