The accurate pointing and control of satellites affects the transmission of voice and data communications transmitted through satellite networks. Three inventors from Boeing Satellite Systems—Yeong Wei Wu, Douglas Hein, and David Augenstein—have patented a method and apparatus for controlling spacecraft. The patent involves stellar inertial technology, which uses star trackers for determining the orientation and position of satellites relative to the Earth. Star trackers are on-board telescopes that scan areas in space and digitally record the position and brightness of stars. Processors onboard the satellites compare the digitally recorded images to star maps stored in memory for determining the spacecraft's exact position. The co-inventors discovered that by rotating the star tracker 45 degrees so that imaged stars cross pixels on a diagonal path, they reduced errors by 50%. "The reduction in image errors allows for the precision pointing accuracy called for in a number of leading-edge satellite systems," says Loren Slafer, a chief technologist at Boeing Satellite Systems.

Design engineer compensation varies widely by location. If you live in Boston, your salary will average more than $90,000, nearly $20,000 above the national average. But if you live in Cleveland, your salary will average almost $10,000 below the national average.
A theme that was reflected in several ways at NPE 2015 was the use of 3D printing to assist in, or improve on, injection molding, as well as improvements in 3D printing materials and processes that are making better functional prototypes and end-use parts.
For many years, it was believed that the strongest biological substance on Earth was spider silk, but new research says aquatic snails produce an even stronger material that could disrupt manufacturing forever.
Most everyone thinks they are ready for an emergency or a disaster. Most everyone is wrong. But engineers are a unique position here as both the designers and beneficiaries of emergency preparedness systems.
