Last week, BAE Systems quietly announced that it had won a $50m contract to further develop the ARGUS system in conjunction with U.S. Defense Advanced Research Projects Agency (DARPA ). ARGUS (or Autonomous Real-time Ground Ubiquitous Surveillance) provides real-time, high-resolution, video surveillance capability for U.S. combat forces for detecting, locating, tracking and monitoring events on battlefields. It is being designed to be used with drones or small manned aircraft.
This latest contract, to develop an infrared capability for ARGUS so that it can be used at nightime, come a few months after few months after BAE Systems admitted that ARGUS had been successfully tested by DARPA in Autumn 2009.
In a helpful article, ARES explains that ARGUS
“is designed to overcome the narrow “soda-straw” field of view of conventional surveillance sensors by providing multiple real-time video streams …. DARPA says ARGUS can provide up to 65 “Predator-class” steerable video streams. The 1.8-gigapixel sensor has four optical telescopes, each with 92 5-megapixel focal-plane arrays – cellphone camera chips, says BAE. The airborne processor combines the video output from all 368 arrays together to create a single mosaic image, with an update rate of 12-15 frames a second.
On the ground, the operator can create windows around stationary or moving targets within the image and ARGUS will down-link the video for these windows in real time. The system provides up to 65 640 x 480-pixel video streams simultaneously, limited only by data link capacity. Also a “global motion detector” mode looks at the entire image and tags potential targets with low-res image “chips”.
In other words, one drone will be able to track, in real time, up to 65 targets and as Wired.com suggests, monitor them over and area of 65 miles.
With up to 65 simultaneous video streams ARGUS easily beats the famously named ‘Gorgon Stare’ which was being developed to have 12 video streams.
ARES has also posted some fascinating images of what ARGUS is capable of doing.
The old adage “you can run, but you can’t hide” is becoming more true than ever, and real-time surveillance of huge swathes of territory using drones seems to be just over the horizon.
