brand equipment provides robust, high quality beyond-line-of-sight
communications with or without satellite space segment
General Dynamics C4 Systems has released a series of innovative
multi-mode tactical terminals under the VertexRSI brand that allow
communication via satellite (using C-, X-, Ku-or Ka-Band) or via
troposcatter (and/or diffraction or line of sight) in highly
transportable, self-contained, field-configurable packages. The
terminals incorporate modern, industry-leading carbon fiber,
truck/trailer-mount or "fly-away"
antenna systems to suit a variety of applications. Now, quickly
deployable tactical terminals can be utilized for reliable,
high-speed troposcatter communication links that compete effectively
with the utility and ease-of-use associated with satellite
A novel Ku-Band troposcatter antenna
feed system generates simultaneous dual beams in the elevation
plane, facilitating "angle diversity"
transmission and eliminating the need for the second antenna used in
conventional troposcatter terminals. Diffraction-mode and
line-of-site communication are also readily accommodated with the
terminal configured for troposcatter operation. Custom-tailored
electronic products facilitate straight-forward terminal setup and
operation with minimal equipment change and maximum versatility. An
auto-acquisition terminal control system provides deploy, acquire,
track and stow functions, as well as supervisory control of RF and
baseband components for streamlined terminal operation.
Beyond bringing troposcatter
communication capability into a modern paradigm for tactical
terminal transportability, VertexRSI has set a new standard for
troposcatter link performance with the TM-20 Troposcatter Modem.
With quad-diversity data rates to 20 Mbps, dual-diversity data rates
to 40 Mbps and unmatched Eb/No and delay spread performance, the
TM-20 has literally redefined troposcatter link capability.
From antennas and modems to properly
engineered turnkey solutions, General Dynamics now offers the most
complete line of troposcatter products and services, from L-Band
through Ku-Band. These cutting-edge products provide exceptional
value and capability for any application, whether
tactical/transportable or fixed.
Roger Wieting, General Manager of
Projects and Technical Services said, "Effective
communication beyond line-of-sight or over-the-horizon (nominally to
150 miles) has been accomplished for many years using troposcatter
links. But, until now the use of troposcatter has been associated
with bulky, power-hungry equipment and relatively low data rates.
Our troposcatter communication products have allowed us to
re-define the look, feel and performance of troposcatter systems,
with a significant expansion of previously accepted performance
new multi-mode terminals build upon our industry-standard line of
highly transportable tactical SATCOM terminals, sharing a mature,
field-proven platform," Wieting said.
"With dual-mode tropo/satcom capability,
users have the ability to establish either SATCOM or troposcatter
operation in the field, depending upon the deployment situation. In
addition, many existing VertexRSI tactical terminals already in the
field can be readily upgraded with troposcatter capability."
