Avid cruciverbalists amongst us appreciate that each week I create a new crossword puzzle that has a theme related to engineering, mathematics, chemistry, physics, and other technical words. You will never be asked the name of a movie star unless he/she was involved in a technical endeavor (e.g., Hedy Lamar). Enjoy! ...
"The Air Force is moving ahead with its delayed GPS III constellation, awarding Lockheed Martin a $395M contract modification for the ninth and tenth of what will be a 32-satellite constellation. Deployment of the third generation of the Global Positioning System, which is expected to have a 25% longer lifespan, three times the accuracy and eight times the anti-jamming capability of GPS II, has been delayed by funding cuts and some technical problems ..."
"To address the need for radio systems that can adapt to changing environments on the fly and that can be easily reconfigured once they're in the field, our engineers have developed the innovative MATRICs (Microwave Array Technology for Reconfigurable Integrated Circuits) chip. MATRICs helps address the future requirements of communications, electronic warfare, and signal intelligence systems. The new, general-purpose chip enables engineers to develop customized radio systems without the need ..."
Hams take note! Here we go again with power line carrier schemes. "AT&T has unveiled its Project AirGig experimental program that aims to use power lines as a way to extend internet access to hard-to-reach users in urban, rural and underserved parts of the world. The first field tests involving Project AirGig technologies are set to begin in 2017 through AT&T Labs, the company said in a September 21 announcement, with the goal of eventually delivering low-cost, multigigabit wireless internet ..."
This is a great resource provided by Charan Langton, retired from Loral Space Systems. "Communications is not an easy science. The math is heavy, and intuition is slow to develop. To complicate things further, the field does not stay put. New concepts are always coming to the fore. This website offers tutorials I have written on various topics in analog and digital communications that will help you cut through this complexity. I keep adding to this collection, albeit very slowly. Our field represents a pinnacle of human achievement ..."
