Military Microwaves Supplement
SATELLITE 2012 proved it is the center of the satellite communications universe with a record 11,000 attendees from more than 70 countries. With about 350 exhibitors, this is a nice ratio of attendees to companies (compare this to IMS/MTT-S that only has about 9,000 attendees with over 550 companies exhibiting so there are far less customers at the show). There were various sessions that cover topics of importance to the industry in addition to panels, roundtables and user discussions. The application areas include military/government, commercial, broadcast, mobility, telecommunications and others.
SATELLITE 2012 kicked off with the opening of the Exhibit Hall and Pre-Conference program featuring 6 tracked forums last Monday. The Conference began the next day starting with The Big Four: At the Center of the Satellite Universe where chief executives from the world’s four largest satellite operators will discuss the future of the satellite marketplace. Interference and capacity issues are always much talked about topics and discussed extensively. Among the component manufacturers, there was much talk about GaN replacing GaAs for more efficient, lighter and smaller units. While there will always be a battle between technologies, TWTs are still alive as I saw a couple of compact 700 W Ka-band amplifiers where GaN has not yet ventured much.
My first meeting was with Martin Coleman who leads the Satellite Interference Mitigation Group which addresses the problem of RF Interference that affects all satellite operators. Technology such as auto deploy and the decreasing size of antennas are contributing to the problem along with streamlined operations, installation and the lack of training are just some of the areas where interference is caused. He said the about 96% of the problems are due to us interfering with each other and only about 4% is actually people purposely jamming signals. So the problem needs to be owned by the industry which needs better training and quality equipment. He is proposing that everyone adapt a carrier ID so that interfering signals can by quickly identified and the problems fixed to reduce the costs of problem investigation and down time. We hope to get an article on the subject for our August Satellite and mmWave themed issue.

We visited the show floor and here are some highlights from the companies we visited:
The most interesting product I saw was the Harris Reconn system which combines a spectrum analyzer, power meter, multimeter, compass, inclinometer, GPS receiver, magnetic declination map and a laptop into a box that is about 12 X 7 X 5” in size (less than 8 lbs). This small box is all that is needed to setup and maintain a satellite communications terminal. It features an intuitive touch screen interface, integrated trouble shooting workflow, spectrum analyzer with DVR capability, remote monitor, power meter, multimeter, LNB tester and wireless operation. Here is a video demonstration of the unit:Avcom was displaying their compact spectrum analyzers which measure 5" x 7" so that it can easily be integrated into another piece of equipment, inside a small satellite terminal, or as an integral part of the satellite antenna itself. The single board design requires only external +15-24 VDC/9 W and a wideband input signal (950 to 2150 MHz) and is available with USB, Ethernet, and Serial communication ports (see photo).
