High-cost satellites remain vulnerable to low-cost threats

By:

WASHINGTON ― Despite advances in satellite technology, many of the U.S. military's most expensive and necessary assets remain vulnerable to jamming from inexpensive tools, according to a new report from the CSIS Aerospace Security Project.

“The technology needed to jam many types of satellite signals is commercially available and relatively inexpensive,” the report reads. Other electronic threats such as spoofing, which attempts to trick receivers into believing manipulated data from an attacker is real, also offer low cost options to adversaries who hope to interfere with satellite connectivity. These kinds of attacks can disrupt communications or position, navigation and timing techniques.

The report, released April 12 and titled “Space Threat Assessment 2018,” notes that while United States near-peer adversaries have made strides in more advanced kinetic weapons, such as direct ascent anti-satellite weapons, jamming technology also is seen as critical. For example, “China has made the development and deployment of satellite jamming systems a high priority,” according to the authors, Todd Harrison, Kaitlyn Johnson and Thomas Roberts.

Another near-peer, Russia, has displayed jamming and spoofing capabilities in the ongoing conflicts in Ukraine and Syria in the last several years. The report said the use of Russian technology in these conflicts “demonstrate[s] that Russia retains advanced electronic attack capabilities, despite some analysts' claims that Russia's ability to jam and spoof satellites has declined since 1991.”

But the threat from jamming and spoofing attacks goes beyond near-peers. Iran and North Korea, so-called rogue states, also have demonstrated the capability and willingness to interfere with satellite communications and GPS signals, according to the report.

And the ability to jam and spoof signals is likely to spread. The report notes once a jammer or spoofer is developed, “it is relatively inexpensive to produce and deploy in large numbers and can be proliferated to other state and non-state actors.”

But the United States is not sitting by idly. The Air Force's Advanced Energy High Frequency satellites, reserved for secure communication, “incorporate a high degree of protection against jamming, spoofing, and other forms of electronic attack,” according to the report.

The U.S. is also preparing troops to operate in GPS-denied environments. In January, the Defense Department jammed GPS-signals in western states so pilots could train in environments that will likely come to characterize combat in the age of electronic warfare.

    NASA Invites Media to Observe Quiet Supersonic Flight Series Operations

    NASA is inviting journalists to learn about the agency's Quiet Supersonic Flights 2018 campaign during a media day event taking place Friday, Nov. 9, in the Houston area. Test pilots and project leads will be available for interviews and to share information about the flight series, known as QSF18, and its contributions to NASA aeronautics research. Media also will get a close-up look at flight operations with NASA's F/A-18 research aircraft as they are used to test community response over Galveston, Texas, using a “quiet thump” technique designed to reduce loud sonic booms typically associated with supersonic flight. The event is scheduled to begin at 10 a.m. CST at Ellington Field, just north of NASA's Johnson Space Center in Houston, then moves to Galveston, where QSF18 field team members operating microphone stations will measure sound levels. Reporters will have an opportunity to observe the field equipment and interview personnel during periods between quiet thumps. Media planning to attend must contact the Johnson newsroom at 281-482-5111 before 4 p.m. Wednesday, Nov. 7. The event is weather dependent. Should inclement weather occur, please contact the Johnson newsroom for more information. The QSF18 campaign is a cooperative effort involving NASA's Armstrong Flight Research Center in Edwards, California, Johnson, and NASA's Langley Research Center in Hampton, Virginia.
