Exclusive: the high-altitude balloons promise a cheap monitoring platform that could follow multiple cars and boats for extended periods
The US military is conducting wide-area surveillance tests across six midwest states using experimental high-altitude balloons, documents filed with the Federal Communications Commission (FCC) reveal.
Up to 25 unmanned solar-powered balloons are being launched from rural South Dakota and drifting 250 miles through an area spanning portions of Minnesota, Iowa, Wisconsin and Missouri, before concluding in central Illinois.
Travelling in the stratosphere at altitudes of up to 65,000ft, the balloons are intended to “provide a persistent surveillance system to locate and deter narcotic trafficking and homeland security threats”, according to a filing made on behalf of the Sierra Nevada Corporation, an aerospace and defence company. [...]
rthur Holland Michel, the co-director of the Center for the Study of the Drone at Bard College in New York, said, “What this new technology proposes is to watch everything at once. Sometimes it’s referred to as ‘combat TiVo’ because when an event happens somewhere in the surveilled area, you can potentially rewind the tape to see exactly what occurred, and rewind even further to see who was involved and where they came from.” [...]
The new balloons promise a cheap surveillance platform that could follow multiple cars and boats for extended periods. And because winds often travel in different directions at different altitudes, the balloons can usually hover over a given area simply by ascending or descending.
Neither Sierra Nevada nor US Southcom responded to requests for comment on this story. However, the rival balloon operator World View recently announced that it had carried out multi-week test missions in which its own stratospheric balloons were able to hover over a five-mile-diameter area for six and a half hours, and larger areas for days at a time. _______________________________________________ nexa mailing list nexa@server-nexa.polito.it https://server-nexa.polito.it/cgi-bin/mailman/listinfo/nexa
