 Two Sides of the DoD Coin: Budgets Slashed, UAV Market Soars
By Fred Ortiz, President
dB Control
As we embark on a new year, imminent cuts to the U.S. Department of Defense (DoD) budget are top of mind for those of us in the military electronics market. At a recent House Armed Services Committee hearing, the nation’s military chiefs cited a $600 billion defense cut as “catastrophic to the military” and having a “severe and irreversible impact.”

LightSquared:
The Show’s Over
…Or Should Be
By Barry Manz
There are a lot of very technically astute people at the Federal Communications Commission. Many have decades of experience at every level of RF and microwave technology. How then might LightSquared’s proposal for a satellite/terrestrial LTE network have ever gotten past its first hurdle? Even a cursory inspection of the plan, in which the company's network would operate extremely close to GPS frequencies at L-band, makes interference to GPS devices almost a certainty. Read More...

| Latest Amateur Satellite Functioning Normally |
After a variety of battery-oriented issues, amateur radio's newest satellite (ARISSat-1/KEDR) appears to be functioning normally after being deployed from the International Space Station by three cosmonauts on August 4. Deployment of the satellite, built by amateur radio operators and designed to interest students in scientific and technological careers, was broadcast on NASA TV. The spacecraft is designed to provide UHF uplinks and VHF downlinks for use by hams, provide images from four cameras, recharge the satellite’s battery using solar panels, and transmit audio greetings in a variety of languages that can be received by simple radios or scanners. It also houses an experiment from Russia's Kursk University that measures atmospheric pressure. The satellite is a cooperative effort between the Radio Amateur Satellite Corp. (AMSAT), Amateur Radio on the International Space Station (ARISS), the Russian space agency RSC-Energia, and NASA. Design, development, and construction of the satellite were performed by AMSAT volunteers.
