Just as the proving ground for automotive technology is the
racetrack, research in GPS (global positioning system) has always happened on
the battlefield.
The U.S. government began using satellite signals for submarine
navigation in the 1960s. Today, the system has evolved so the 24 satellites
circle Earth in six orbital planes with each satellite passing over a given
point every 24 hours. Users gain a four-dimensional fix (x, y, z axes and time)
by triangulating between the time lags of signals received from any four
satellites.
The whole system is controlled from Schriever Air Force Base in
Colorado Springs, CO (www.shriever.af.mil), and works so well
that the military scrambled the signals, allowing civilians accuracy only within
100m. But after President Clinton ordered them unscrambled in May 2000, the GPS
system began working within a fraction of that error, spawning new consumer
applications in cars, boats, cell phones, and pagers. (The U.S. military can
still re-scramble them regionally at any time).
Now KVH Industries (www.kvh.com)
is returning to the system's roots for its latest advance-the TACNAV(TM)
tactical navigation system for armored vehicles. The product provides position
data for every vehicle, even navigating by dead reckoning when satellite signals
are jammed. And it creates a single interface that includes the vehicle location
and azimuth, gun turret angle, and target location. It has a contract to supply
the systems to an undisclosed Southeast Asian country.
By refining topologies and using new fluid technology, Moog's new peak sine drive controller increases available power without increasing controller volume.
Lantronix Inc. has expanded its line of controllers for sensor networks with the release of a rugged controller that improves management of automation systems used in a number of industries, including manufacturing, oil and gas, and chemicals.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
