Resilient GPS Timing Selected for Defense Against Hypersonic Weapons

Raytheon Missiles & Defense selected Orolia’s rugged time and frequency system to support its Lower Tier Air and Missile Defense Sensor (LTAMDS) radar program, an advanced air and missile defense system. The LTAMDS stands on the front lines of U.S. countermeasures against advanced and next-generation threats including hypersonic weapons, flying faster than a mile a second. Among the Orolia timing system’s qualifications for the program were its with its low size, weight and power (SWaP); further specifications are classified.

Contracted by the U.S. Army in October 2019, LTAMDS consists of three antenna arrays, a primary on the front and two secondary arrays on the back. Together the three detect and engage multiple threats from any direction at the same time. This produces a battlefield without blind spots, according to Raytheon. Orolia’s xxx use GPS signals for timing, frequency and network synchronization across critical military systems.

LTAMDS’ primary array is about the same size as the array for the Patriot Air and Missile Defense System, but has more than twice the power. It is designed for the U.S. Army’s Integrated Air and Missile Defense system, and will also preserve existing military customers’ investment in the Patriot system.

Critical Timing

Orolia was chosen for the LTAMDS program based on its core expertise in resilient timing and configurable ruggedized PNT systems for challenging environments. The company has successfully delivered time and frequency platforms for other Raytheon programs of record.

Orolia was the first company to receive approval for a time and frequency reference system on the Defense Information Systems Agency (DISA) Department of Defense Information Network (DoDIN) Approved Products List for network interoperability, with its SecureSync system.

“Ultra-precise mission timing and sync technology are fundamental building blocks for the Resilient PNT systems that warfighters rely on for continuous operations in contested environments,” said Hironori Sasaki, president of Orolia Defense & Security.

Orolia supplies a range of products in end-to-end NAVWAR and Resilient PNT solutions to protect, augment and strengthen military systems for GPS-denied environments, from critical timing solutions to GPS/GNSS simulation, interference detection, and mitigation. Orolia Defense & Security provides resilient PNT solutions and custom engineering services to U.S. government agencies, defense organizations, and their contractors, and is authorized to work on the full spectrum of U.S. government classified and unclassified projects.
