Agency Addresses Hypersonic Vehicle Detection, Satellite Survivability
JAN. 12, 2022 | BY DAVID VERGUN
The Space Development Agency will be fielding satellites that will provide eyes-on capability to detect maneuverable hypersonic glide vehicles during flight, and those satellites will be affordable and prolific, the SDA director said.
Satellites in LEO can detect those dim heat signatures better than satellites in higher orbits, he added. Also, if there are several satellites doing the tracking, getting a geometric fix on a hypersonic threat is much more precise.
Once the data gets fused in the Joint Overhead Persistent Infrared Ground System, it’s then disseminated out typically over UHF or other Link 16 networks, then to weapons platforms.
By September 2024, plans are that 144 transport layer satellites will begin to be launched; that will result in initial warfighting capability, forming a mesh network, he said.
In 2024 or 2025, 28 tracking layer satellites will be launched, resulting in global coverage, he said.Spotlight: Science and Tech
The commercial sector has enabled the growth of this military capability as the prices of satellites and rocket launches have plummeted and as technology has dramatically improved, he said.
Addressing concerns about overcrowding space with satellites, Tournear said space is big, and the higher one goes up in low-Earth orbit, the more room there is.
The goal of putting a large number of small satellites in space, he said, is to create redundancy in the event an adversary tries to take them out with anti-satellite weapons. It would be much harder to disable the network.
The SDA, established in March 2019, will transfer to the Space Force in October 2022, Tournear noted.
