Close Support: Compact VSAT Systems for Mission-Critical Applications, by Gabriel Racah, Director of Marketing, ORBIT Communication Systems
Todays world is truly connected with a wide range of technologies that allow communication in homes and workplaces in cafes and airports and while were on the road. But demand for always-on connectivity goes way beyond the reach of terrestrial and cellular coverage, from special forces with a mandate to report mission-critical field imaging to passengers of ocean-going cruise ships who wanting to log on their favorite social networks. The expectation to be online at all times is truly global.

Focus: AEHF Beam Forming Network, by David Rhodes, a principal engineer within the Defense & Space Division of EMS Technologies
The U.S. Air Forces Advanced Extremely High Frequency (AEHF) system is the nations next-generation military strategic and tactical relay system, which will deliver survivable, protected communications to U.S. forces and selected allies worldwide. When fully operational, the system will consist of four crosslinked satellites, a ground mission control center and user terminals. The AEHF system provides joint, interoperable, assured connectivity for warfighters in operations in all levels of conflict, a capability not available through other planned military communication networks.1 The satellite serves as a smart switchboard to establish, maintain, reconfigure and disassemble required communications circuits as directed by the users. The terminals will provide encrypted voice, data, teletype, or facsimile communications.2 One key to the success of this communications satellite is the ability to provide reliable, high speed, secure, anti-jamming, survivable tactical communications capability. The AEHF beam-forming network (BFN) is at the heart of one of these on-board systems.
Focus: Event Global Milsatcom 2011, London, United Kingdom
Occassionally, one cannot see the forest for the trees... technology advances for MILSATCOM occur on a daily basis, and keeping abreast of such information is becoming more and more difficult. However, there can be no excuses... the very viability of a company could rest on the next advancement, and if it remains outside the realm of cognizance, opportunities may well be missed.
TechInt: Digital Video Off Boresight, by Dan Makinster and George Mancuso, Agile Communication Systems, and Dr. Yendo Hu, Sculpture Networks
Video is pervasive in consumer and military applications and the video requirements are constrained by both similar, and different, factors. The need to deliver consumer video to a large audience is primarily governed by available bandwidth. The military and other government agencies, although working with a smaller audience, are also restricted by bandwidth. In addition, they also have a need to deliver video in real-time.
