Orolia Selected by Raytheon to Support U.S. Army LTAMDS Radar Program

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

Raytheon Missiles & Defense was selected by the Army in October 2019 to provide the next-generation LTAMDS, which is an advanced air and missile defense radar. The LTAMDS system will help the U.S. Army defeat advanced threats, including hypersonic weapons.

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 the industry leader in end-to-end NAVWAR and Resilient PNT solutions to protect, augment and strengthen military systems for GPS-denied environments.

Raytheon LTAMDS radar

Raytheon’s LTAMDS is a 360-degree, Active Electronically Scanned Array (AESA) radar powered by company-manufactured Gallium Nitride (GaN), a substance that strengthens the radar signal and enhances its sensitivity.

LTAMDS consists of a primary antenna array on the front of the radar, and two secondary arrays on the rear. The radar antennas work together to enable operators to simultaneously detect and engage multiple threats from any direction, ensuring there are no blind spots on the battlefield. LTAMDS’ primary array is roughly the same size as the Patriot radar array, but provides more than twice Patriot’s performance.

While it is designed for the U.S. Army’s IAMD system, LTAMDS will also be able to preserve previous Patriot investments.

Raytheon is working closely with hundreds of suppliers across 42 states, including a core team playing a strategic role in building the LTAMDS solution. They are Crane Aerospace & Electronics, Cummings Aerospace, IERUS Technologies, Kord Technologies, Mercury Systems and nLogic.
