New TM-20 modem offers three-fold improvement in data transfer speeds

General Dynamics C4 Systems, a business unit of General Dynamics and Radyne Corporation are introducing and marketing a new Troposcatter or “over-the-horizon” modem. The new product, called the TM-20 modem, is being showcased at U.S. Military Communications seminars and events such as the recent Product Improvement Working Group and Conference in Perry, Ga.

The TM-20 is being developed by Radyne in partnership with General Dynamics C4 Systems and will be marketed exclusively under the General Dynamics VertexRSI® brand name. The TM-20 represents a quantum leap in Troposcatter communications technology, facilitating data transfer at speeds up to 20 Mbps, a nearly three-fold improvement over any other over-the-horizon system available today. The modem also provides increased support for a variety of communications techniques to maximize transmission range and data integrity.

The U.S. military currently employs AN/TRC-170 Troposcatter systems using 1980’s technology for tactical and strategic communications throughout the world, with a number of terminals currently deployed in the Middle East.

Bob Fitting, Radyne Corporation’s chief executive officer, said, “We are excited to unveil this new technology. The TM-20 represents the first significant advance in over-the-horizon technology in almost three decades. The use of modern signal processing techniques and a patented channel-directed-equalizer provides for link performance and configuration flexibility previously unheard of in Troposcatter systems. Today the concentration of technology in the TM-20’s single, two-unit chassis (four inches high, by 19 inches wide and 18 inches deep) provides functionality and performance well beyond what was achievable using entire racks of equipment only a few years ago.”

Jeff Porter, general manager of VertexRSI Antenna Products for General Dynamics, added, “The TM-20 provides a technically superior core for the next generation of beyond-line-of-sight communications terminals, which will include highly configurable antenna and RF systems. Our experience and broad portfolio of existing antenna and RF products, coupled with the technology Radyne brings in the TM-20, yields field-configurable mobile and tactical terminals capable of unsurpassed performance in satellite communication or Troposcatter modes of operation.”
