Symmetricom
Symmetricom is the world leader in generation, synchronization and distribution of precise time and frequency signals. 20,000 kilometers over the earth, Symmetricom products are at work, providing the precise time, frequency and synchronization signals required by a network of GPS satellites. Around the globe, the international timescale is set to sub atomic precision using Symmetricom frequency reference. Our timing solutions are critical to radio navigation in coastal waters, deployment of missiles, the seamless delivery of voice, data, and video across telecom and cable networks, and uninterrupted availability of power to millions.
We put our expertise to work designing, manufacturing, and delivering atomic clocks, network synchronization, and timing solutions used in wireline and wireless telecom networks, cable networks, space, defense and avionics systems, and enterprise IT networks. Our customers include network and cable service providers, telecom and cable equipment manufacturers, military and aerospace contractors, global enterprises, as well as government and research facilities in over 90 countries.
SOLUTIONS
GPS Solutions
Symmetricom GPS solutions provide the highest level of time and frequency accuracy with our primary reference sources, time and frequency generators, receivers, and other GPS related instrumentation. Our GPS and time code instrumentation solutions support multiple applications and a wide customer base, from assuring wide availability of precision time and frequency throughout a telecom network to securing critical satellite and ground based instrumentation with the world’s most powerful, accurate and versatile Selective Availability Anti-Spoofing Module (SAASM) based GPS time and frequency receiver.
Time & Frequency Distribution
Perfect timing. At Symmetricom it’s more than a slogan. Around the world, Symmetricom products provide the accuracy and precision required to set the clocks of the international timescale. That means millions of people depend on our cesium, rubidium, and quartz frequency reference standards to deliver atomic clock accuracy and reliability. Our timing products support the integrity of IT systems of major, multinational companies on every continent, help deploy satellites, aircraft, power stations, and missiles, and assure the performance of critical applications in governments, metrology, and the aerospace industry.
Frequency References
Atomic physics sets the standard for stability and accuracy in precision frequency reference packages worldwide. Hydrogen, cesium and rubidium standards, and quartz oscillators have supported more military communications, satellite ground stations, and test & measurement applications than any other precision frequency references in the world. Advanced research, cutting edge electronics engineering, superior manufacturing, and integrated software design have resulted in precision frequency standards that deliver exceptional performance and unsurpassed accuracy, stability and reliability in the most challenging of environments.
NTP Servers
Symmetricom offers Network Time Protocol (NTP) time servers that provide accurate, reliable, and secure time synchronization to Enterprise IT and telecommunications networks. Our GPS NTP Network Appliances and Modular NTP Solutions make it easy to manage and monitor time synchronization through workstations, servers and routers, thus assuring the highest integrity and QoE throughout the network.
IEEE 1588 PTP Solutions
IEEE 1588 (also known as Precision Time Protocol or PTP) is the emerging standard for providing precise timing and synchronization over packet-based, Ethernet networks. Symmetricom's best-in-class IEEE 1588 solutions address a wide variety of applications ranging from precise carrier class synchronization and precise time stamping to the test and measurement of PTP networks. These solutions enable Symmetricom customers to directly benefit from lower-cost, higher-capacity packet-over-Ethernet network infrastructures without sacrificing precise timing and synchronization requirements.
Test and Measurement
Symmetricom’s digital, state-of-the-art test sets bring a paradigm shift to the way that phase noise and ADEV measurements are made. What was once a complicated and costly procedure has now been made easier, more accurate, and more cost effective. Typically used to characterize high precision oscillators and atomic clocks, Symmetricom’s test sets are simple one-box solutions that characterize even the lowest noise references more accurately than ever before.
