Expert Advice: Mobile Computing on the Rise

July 1, 2012By

This discussion of current trends in location-enabled mobile devices takes as its foundation the different operating systems (OSs) for those devices. Why? For GPS/GNSS hardware units to be useful, there have to be software applications — apps — also riding on those units. Apps are totally dependent on the operating system. An analogy is that the operating system is the foundation of a house and the app is the house itself. The type of foundation you have drives what type of house you can build. read more

In business, it’s all about location, and in military circles, something called real-time situational awareness, driven by the ready availability of PNT from GPS. However, it has been reported (and validated by experience) that U.S. soldiers believe that the GPS equipment they are issued through official channels is too big, too heavy, uses too many batteries, and is old-looking and not sexy like the multi-color, multi-app personal electronics and smart phones they are accustomed to at home. read more

Wheat is the world’s second staple food, and bread its main product. Bakers have been around for 30,000 years.
