  　　A brief history of Trimble and GPS
  　　Great advances of every age are created by pioneers–visionaries who look beyond the visible in search of new lands, new ideas, new technology, new goals for mankind. Trimble company founder Charlie Trimble is such a visionary.

　　In the early 1980s, when Trimble's fledgling company was developing marine navigation products, the Global Positioning System was an emerging technology with exclusively military applications. Trimble was intrigued by the Department of Defense-funded location system which, when complete, would include 24 orbiting satellites and their ground stations and make it possible to address every point on the planet, with absolute precision, simultaneously. Recognizing the vast potential of the new technology, the company focused its resources on researching, developing and marketing products that would harness and expand the power of GPS, spurring commercial and consumer applications as well as military use
