t Tecknow FIRST IS IT A DRONE OR A SATELLITE? The StratoBus offers long endurance and complete autonomy from a fixed position Photograph: Thales W With UAVs crowding navigable airspace and plans underway to put giant mega-satellites into orbit, it was just a matter of time before a drone-satellite hybrid was developed to fit between the two spaces. StratoBus, a new project out of France, is conceptualised to do just that. Designed to be about the length of a football field and 25 yards in diameter, the blimp-shaped vehicle’s shell will be made of carbon fibre. Without a launcher, StratoBus floats to the lower stratosphere at an altitude of about 21 km where developers say it will be in a perfect position to carry out a range of functions, including surveillance, border security monitoring, communications reinforcement and facilitating navigation, all from a stationary position with the help of two self-adjusting electric motors. StratoBus will be able to endure missions of up to a year with a total lifetime of five years. The ultra-lightweight design allows for a plug-and-play ^KB
