Frequency Electronics, Inc. was founded in 1961 and is now a well-established public company in Long Island, New York, and trades on the NASDAQ Stock Exchange under the symbol FEIM.
It has four wholly-owned subsidiaries: FEI Communications Inc. and FEI Government Systems Inc., located in Mitchel Field, New York; FEI-Zyfer Inc., located in Garden Grove, California; and FEI-Elcom Tech Inc., located in Northvale, New Jersey.
FEI and its subsidiaries are major worldwide suppliers of Precision Time and Frequency (PT&F) products for ground, seaborne, airborne, and space terminals and platforms used by commercial and government/military systems suppliers.
The Company transformed itself from a defense contract manufacturer into a high-tech provider of precision time and frequency products used to synchronize voice, data and video transmissions in wireless communications systems. These systems are found in both ground-based stations and on-board satellites.
The Company also continues to support the United States government with custom based solutions and products for defense or space applications but it will do so with more emphasis on COTS (commercial off-the-shelf) products than on contract-based projects.
What We Do
Terrestrial Wireless:
For the terrestrial secure command control and communications systems market, the Company’s products support multiple C4ISR and EW applications for the U.S. Government on land, sea and air-borne platforms. Recently identified threats to the communication capabilities of U.S. Government facilities through jamming or “spoofing” global positioning systems (“GPS”) signals may be mitigated by the Company’s technologies. In addition, similar types of threats to the public and enterprise networks have been identified by the U.S. Department of Homeland Security. The Company’s high precision, ruggedized clocks combined with specialized software are essential for certain secure communication systems.
Space-based:
For the satellite market, the Company has a unique legacy of providing master timing systems, power converters, and frequency generation, synthesis and distribution systems. These products are applicable for both commercial and U.S. Government enduse. Currently, there are approximately 3,400 satellites with varying remaining useful lives operating in Geostationary, Medium and Low Earth Orbits. The U.S. government operates approximately 1,900 of these.
The number of operational satellites with emphasis on high-throughput is expected to continue to grow over the next ten years as demand for higher bandwidths and improved anti-jam-antispoofing increases. Furthermore, the U.S. Government is expected to contract options for additional GPS III satellites, and the Company is well positioned to compete for the onboard clock ensemble with its high-precision digital Rubidium atomic frequency standard.
The commercial use of satellites launched for communications, navigation, weather forecasting, video and data transmissions has led to the increased need and ability to transmit information to Earth- based receivers, which requires precise timing and frequency control of the satellite systems. FEI has provided the following products to the satellite industry:
- Master clocks (Quartz Crystal Oscillators and Rubidium Vapor Atomic Oscillators)
- RF-Chains ( frequency synthesis and distribution)
- Up-Down Converters
- DC/DC Converters
- Space-rated Hybrid assemblies
