Since 1961, Long Island-based Frequency Electronics has designed and manufactured precision timing, frequency-control and synchronization systems for demanding space, defense, communications and other terrestrial applications. Its vertically integrated operation produces key building blocks such as quartz resonators and rubidium atomic clocks in-house, while subsidiaries FEI-Zyfer and FEI-Elcom Tech extend the business into GPS-based assured positioning and RF microwave systems. FEI’s timing technology has supported more than 120 space programs, including the GPS III satellite constellation.
