USSF’s Space Systems Command’s DARC combined the capability of multiple ground-based antennas at DARC Site 1 in Western Australia. The calibrated antenna arrays operate as a single system to characterise the movement of multiple satellites.
This technology, say the organisations,will create the world’s most capable deep-space tracking radar system. Basically, the technology will be capable of tracking spacecraft that present threats to space assets or the U.S. itself and allies. It is a partnership between Australia, the United Kingdom, and the United States (AUKUS).
It will track very small objects in, to, and from geosynchronous orbit (GEO).
Tracking
“Northrop Grumman’s DARC will provide a strategic advantage at a scale never before achieved in global space domain awareness,” said Kevin Giammo, director of Space Surveillance and Environmental Intelligence at the U.S. defence technology company.
“Its ability to track multiple small moving objects over 22,000 miles above earth will offer unmatched persistent and comprehensive capability as the world’s premier deep-space radar tracking system.”
Antennas
Specifically, during the demo, DARC used seven of the 27 antennas at DARC Site 1. Doing this, it sustained a multi-week campaign of data collection, analysis, and adjustment to confirm successful calibration and operational capability.
The demo brings the DARC programme another step closer to full operational capability at Site 1.
Once complete, DARC’s ground-based sensor network will provide full global coverage.
Unlike telescopic systems which attempt this function today, DARC is not impacted by clouds and can operate 24/7. During the night and daylight hours and all-weather conditions.
