Stratobus will be positioned at an altitude of about 20 kilometers (12 miles) over its theater of operations, in the lower layer of the stratosphere, which offers sufficient density to provide lift for the balloon. Winds at this altitude are moderate and stable throughout the entire zone between the tropics, at not more than 90 km/h (55 mph), allowing the airship to remain stationary by using its electric propulsion system. Stratobus will carry payloads to perform missions such as the surveillance of borders or high-value sites, on land or at sea (videosurveillance of offshore platforms, etc.), security (the fight against terrorism, drug trafficking, etc.), environmental monitoring (forest fires, soil erosion, pollution, etc.) and telecommunications (Internet, 5G).
