 Following on the heels of a recent June 2006 communications breakthrough, Raytheon Company has achieved another important milestone in troposcatter (TROPO) solutions. Besting its own industry-first 20 megabytes per second (MBps) Ku band TROPO or "over the horizon" communications link, Raytheon successfully demonstrated a 40 Mbps link.

This milestone significantly exceeds current TROPO bandwidth rates that today are in the range of 16 Mbps. Increased bandwidth enables soldiers to transmit and receive greater amounts of video and voice data information more quickly.

TROPO is the ability to transmit radio waves over the curvature of the Earth, without using satellites, by bouncing signals off irregularities (small changes in humidity, temperature and pressure) in the troposphere, approximately 6.2 miles (10 kilometers) above the Earth's surface. The U.S. military currently employs TROPO systems for tactical and strategic communications throughout the world.

"Improved TROPO solutions provide our warfighters with access to information without reliance on already overburdened satellites," said Jerry Powlen, vice president, Network Centric Systems' Integrated Communications Systems.

Lockheed Martin Demonstrates Volume Search Radar Antenna For US Navy DDG-1000 Program
 Moorestown NJ (SPX) Aug 18, 2006
 Lockheed Martin has successfully completed an on-time demonstration of the new Volume Search Radar (VSR) antenna for the U.S. Navy's DDG-1000 next generation destroyer program. The demonstration represents the completion of a key milestone qualifying the antenna to move on to the next phase of radar testing, which includes interfacing the VSR antenna with the separate Dual-Band Radar signal/data processor and receiver/exciter cabinet that Raytheon is developing for DDG-1000.
