Rockwell demonstrates new jamming-resistant directional communications link


Rockwell Collins has demonstrated its new directional communications link with longer range and anti-jamming capabilities.

A series of demonstrations was conducted by the company for prime US Department of Defense contractors and government research laboratories.

Each scenario was performed in a different frequency band to highlight the product’s adaptability, according to the company.

The communications link is capable of blocking out jamming and sending signals ten times farther than omnidirectional systems.

Rockwell has reduced the size, weight and cost of its directional technology, as well as made it available to other contractors for use in their own products.

Commenting on the technology, Rockwell Collins Advanced Technology Center vice-president John Borghese said: “This is a major step in communication technology that can be applied to a variety of industries.

"This is a major step in communication technology that can be applied to a variety of industries."

“With increased range, adaptability and jamming resistance, this new technology will enable capabilities in communications and radar previously only available on platforms with significantly higher cost and power available.”

The communications link employs technology developed under the Defense Advanced Research Projects Agency (DARPA) and the Arrays at Commercial Timescales (ACT) programme.

It can point up to eight directions at the same time while simultaneously receiving a variety of signals, Rockwell stated.

Users can block out the jamming and still receive messages by changing the filtering frequency as needed.

The communications link will be suitable for use within military unmanned aerial systems (UAS) or smaller helicopters.
