An advanced air and missile defense radar has been selected to support the U.S. Lower Tier Air and Missile Defense Sensor (LTAMDS) radar program. The system will help the U.S. Army defeat advanced threats, including hypersonic weapons, whose speed greatly exceeds the speed of sound

Orolia’s LTAMDS system – with low SWaP (size, weight and power), rugged time and frequency system – has been selected by Raytheon Missiles and Defense, nominated by the United States Army in October 2019 to provide the next-generation LTAMDS.

The LTAMDS system 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.

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, according to

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.
