Assuring the highest precision and reliability for critical 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. Timing and frequency control technology from Symmetricom 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 secure mobile and global communications, satellite ground stations and satellites in orbit, metrology laboratories, C4ISR effectiveness, and air and sea navigation.
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 address and exceed the most complex and extreme high reliability requirements.
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 are in the forefront of new timing and synchronization solutions for communications and satellite and ground based instrumentation, with our products meeting the stringent framework requirements of C4ISR and DoDAF.
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, and quartz oscillators have supported more military communications, satellite ground stations, metrology laboratories and test & measurement applications than any other precision frequency references in the world.
