Orolia, through its Orolia Government Systems business, has been selected by Raytheon Missiles & Defense to support the U.S. Lower Tier Air and Missile Defense Sensor (LTAMDS) radar program with its low SWaP (size, weight and power), rugged time and frequency system.

The LTAMDS system — an advanced air and missile defense radar — will help the U.S. Army defeat advanced threats, including hypersonic weapons. It is a radar designed to defeat advanced and next-generation threats including hypersonic weapons, or those that fly faster than a mile a second.

LTAMDS has three antenna arrays — a primary array on the front, and two secondary arrays on the back. They work together, detecting and engaging multiple threats from any direction at the same time. This results in a battlefield without blind spots, according to Raytheon.

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

Raytheon Missiles & Defense was selected by the United States Army in October 2019 to provide the next-generation LTAMDS.

Timing from Orolia

Orolia was chosen for the LTAMDS program based on its core expertise in resilient timing and configurable ruggedized PNT systems for challenging environments, together with its proven track record of successfully delivering 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 flagship 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. “We are proud to be a Raytheon Missiles & Defense partner on LTAMDS and other programs that utilize GPS signals for timing, frequency and network synchronization across critical military systems.”

From critical timing solutions to GPS/GNSS simulation, interference detection, and mitigation, Orolia is an industry leader in end-to-end NAVWAR and Resilient PNT solutions to protect, augment and strengthen military systems for GPS-denied environments.

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.
