Developed by the Defense Advanced Research Projects Agency and BAE Systems, The $18.5 million Autonomous Real-Time Ground Ubiquitous Surveillance Imaging System (ARGUS) program will be the most advanced surveillance system in the sky.

Once attached under an unmanned aerial vehicle, an ARGUS camera can patrol at 17,500 feet and send back high resolution images of 1.8 gigapixels.

The images are so crisp and clear that an analyst can actually see what color shirt a subject is wearing.

The following screen grabs from a PBS documentary feature lead BAE engineers saying this is the first time they've been granted permission to show ARGUS' basic features.
