As part of the AETHER project, the UK has successfully completed a stratosphere balloon test for information, surveillance and reconnaissance (ISR) missions.
The test took place in South Dakota, USA, and used unmanned balloons that work between 18,000 and 24,000m altitude. This is much higher than commercial air traffic. Each balloon can be equipped with a maximum of 3kg surveillance equipment, and it has been flew more than five days, and the network consisting of several balloons has provided almost seamless surveillance for about a month.
According to the British Department of Defense, the system is more likely to be utilized as one person can launch and operate even in poor weather. In addition to military applications, the government is seeing the possibility of being used in private sectors such as disaster support, remote area monitoring, weather and environmental data collection. Maria Eagle emphasized that this technology is a progress that improves the military’s ability to operate in a complex environment.
The project was collaborated with English -American companies such as Voltitude, Landguard Systems, and Aerostar. The capacity is currently limited, but the UK is studying a more solid balloon version that can operate for up to one year and have a heavier sensor.
The government sees this technology as a promising alternative to satellite systems or incentive aircraft.
