Assuring the highest precision, reliability and portability for aerospace and defense applications
Because millions of people put their trust in our precision and reliability, we build our products to withstand the most hostile and demanding environments. Symmetricom timing and frequency control technology enables the successful deployment of critical communications, command and control systems as well as rigorous test and measurement applications. Our comprehensive timing and frequency solutions meet or exceed the challenging requirements of such applications as:
- Secure mobile and global communications
- Satellite ground stations
- Satellites in orbit
- Metrology laboratories
- C4ISR
- Air and sea navigation
- Dismounted tactical systems
Avionics and Space
Critical and tactical aerospace applications like radio navigation, satellite transmission, and tracking and guidance systems depend on the ability to continuously and unambiguously identify reference points in time and space. Designed for relative ease of use and absolute success under the most adverse conditions, our cesium and militarized oscillator standards meet or exceed the most complex and extreme requirements for accuracy, stability, reliability and portability.
Defense
Symmetricom’s hydrogen, cesium and rubidium standards, and quartz oscillators support more military communications, satellite ground stations, and test & measurement applications than any other precision frequency references in the world. We constantly stay in the forefront of new timing and synchronization solutions for satellite and ground based communications and instrumentation with products that meet the stringent framework requirements of C4ISR and DoDAF. Innovations like the Chip Scale Atomic Clock enable even the individual soldier to gain lifesaving timing and frequency advantages virtually anywhere, whether on foot or in a vehicle.

An unequaled installed base with a 30-year operational track record. Symmetricom’s precision frequency standards deliver exceptional performance and unsurpassed accuracy, stability and reliability in the most challenging of environments. Our hydrogen, cesium and rubidium standards, our quartz oscillators, and our Chip Scale Atomic Clock (CSAC) have supported more military communications, satellite ground stations, metrology laboratories and test & measurement applications than any other precision frequency references in the world.
