Defending Satellite tv for pc Communications – SpaceNews

A safe system that enables troops on the tactical edge to speak securely

The U.S. Area Power acquires, operates and maintains a constellation of Superior Extraordinarily Excessive Frequency satellites which are reserved for strategic, high-priority army missions, offering safe, jam-resistant communications.

Whereas tactical army forces do use AEHF, its main mission is to offer 100% assured communications for the nationwide command authority and strategic or nuclear forces.

The Division of Protection acknowledged a necessity for a tactical different to AEHF to ensure U.S. warfighters and allies have entry to safe satellite tv for pc communications throughout vital missions and throughout the warmth of battle. The answer: Protected Anti-Jam Tactical Satellite tv for pc Communications or PATS.Advertisement

“We constructed upon among the strengths of AEHF, however the true distinction is that PATS offers extra bandwidth, extra assets, and permits for extra customers,” stated John DeNorscia, product space technical director at Raytheon Intelligence & Area, one of many 4 companies that kind Raytheon Applied sciences.Advertisement

The U.S. Area Power lately awarded Raytheon Intelligence & Area a $500 million indefinite-delivery/indefinite-quantity contract with a $37 million first supply order to develop the Air Power Military Anti-Jam Modem.

The modem helps the Area and Missile Techniques Middle’s Protected Tactical Waveform, an anti-jam functionality working on army satellite tv for pc communication terminals by the Wideband World SATCOM constellation in addition to commercially leased satellites.

“Leasing industrial satellites provides your community extra resiliency, as a result of there’s solely so many WGS birds,” stated Greg Prince, Raytheon Intelligence & Area A3M technical director. “There are much more industrial satellites than WGS satellites, and if the federal government can shield that bandwidth, then it might enhance its world protection.”

Utilizing protected satellite tv for pc communications to direct deployed forces working on the tactical stage is the quickest solution to talk vital intelligence and data. It may be deployed in real-time, anyplace on this planet.

“In right this moment’s surroundings, the whole lot is information-dependent,” stated Mark Hutchins, RI&S senior program director, Protected Communication Techniques. “And the pure solution to get it to our cell deployed forces is through SATCOM….”

PATS makes use of parts of business cryptographic algorithms, permitting it for use in additional harmful and extremely contested house environments. These areas embrace places the place an adversary is monitoring the encryption and decryption of the indicators, and trying to crack the code. PATS additionally transmits knowledge at a really excessive bandwidth, permitting for the streaming of HD video in real-time. One other key good thing about PATS is that it allocates assets dynamically.

“From a community perspective, person terminals are in a position to request extra bandwidth and quit extra bandwidth after they don’t want it over time because the community visitors ebbs and flows,” Prince stated. “PATS goes for use quite a bit for video distribution, however operators received’t be consuming all that knowledge on a regular basis. Once they now not want it, these assets are put again into the pot, they usually’re in a position to be redistributed to different terminals that do.”

Underscoring the significance of satellite tv for pc communications to the Division of Protection, Gen. Jay Raymond, U.S. Area Command commander, signed the “Imaginative and prescient for Enterprise Satellite tv for pc Communications,” Feb. 19, 2020, that emphasizes the robustness and resiliency of satellite tv for pc communications.Advertisement

“Adversaries perceive the benefit SATCOM brings our warfighters and are working to disclaim, degrade, and destroy these capabilities,” states the imaginative and prescient paper.
