Prior to joining the FEI family of companies, Zyfer was an operating division of Odetics Inc., a California technology company which spawned several technology-related subsidiaries. Estab- lished in the mid 1980’s and originally named Odetics Telecom, the division was incorporated as Zyfer Inc. in 1999, and with its acquisition in 2003 by FEI, became a wholly-owned subsidiary of Frequency Electronics Inc., as FEI-Zyfer, Inc.

Based on the expertise garnered over many years as a leading provider of timing, synchronization and frequency reference products to the telecommunications industry, FEI-Zyfer expanded its offerings to include the design, development and manufacture of GPS-based systems needed to address a broad range of government and commercial applications requiring synchronized high-precision position, navigation, timing and frequency references.

From its early successes while part of Odetics Telecom - such as providing more than 6,000 GPS-based synchronization references to support cell sites in South Korea and more than 4,000 position and synchronization references to support E911 overlay services in the United States - FEI-Zyfer has gone on to produce more than 10,000 additional GPS-based Time and Frequency systems for both government and commercial applications such as satellite communications, secure communications, signals intelligence, time and frequency reference and measurement, and time and frequency distribution. FEI-Zyfer’s systems are employed in a wide-range of operating environments, including deployed systems for ground mobile, shipboard and airborne platforms.

FEI-Zyfer was an early adopter of Precise Positioning Service-Security Module (PPS-SM)military-grade GPS Receivers, and was the first Host Application Equipment (HAE) integrator of Selective Availability Anti-Spoofing Module (SAASM) military-grade GPS Receivers. To date, FEI-Zyfer has provided more than 4,000 SAASM-equipped GPS-Disciplined Time and Frequency Reference systems to the U.S. Department of Defense and Agencies, and to U.S. Government-approved Allies through the Foreign Military Sale (FMS) and Direct Commercial Sale (DCS) processes.

FEI-Zyfer's core-competencies are:
  • Design, development and manufacture of COTS and Custom GPS (and GNSS)-based Position, Navigation, Timing and Frequency Reference Systems for use in ground/ ground mobile, shipboard and airborne applications;
  • Performance optimization of our A-PNT&F systems for applications such as:
  • SIGINT, COMINT and ELINT systems which provide precise timing, synchronization and position to support cooperative engagement functions for precise geolocation when employed on ground/ground mobile, shipboard and airborne manned/unmanned platforms;
  • Phased Array Radar, Targeting and Fire Control Systems for Missile Defense;
  • Tactical Data Link GPS-references which support basic and advanced TDL functions including video and precise participant location and identification (PPLI);
  • SAASM PPS and M-Code Disciplined Time and Frequency Reference and Measurement Systems which build, prioritize and monitor an ensemble of external references with differing accuracies and stabilities, including Cesium Clocks, Two-Way Satellite Time Transfer (TWSTT) modems, eLoran Receivers, and Fiber Optic and RF-based modems for Assured - Position, Navigation and Timing requirements in accordance with CJCSI 6130.01F/G;
  • Regional A-PNT&F reference systems for deployed military and agency programs which minimize timing and synchronization dependence on GPS
  • Fiber optic cross-linked Multiple Master and fiber optic cross-linked Master to Multiple Slave systems for maximum redundancy;
  • Resilient system and enclosure designs that maintain required performance levels when subjected to shock, vibration, velocity, 2-D and 3-D acceleration, temperature, altitude, and other environmental conditions typically encountered in deployed applications;
