Since 1983, MTDC has been testing and evaluating GPS (global positioning system) technology for use in the Forest Service, U.S. Department of Agriculture. In the early days, when GPS systems were expensive, bulky, and difficult to use, MTDC worked with the manufacturers to suggest improvements. Now that the technology has matured, MTDC is more involved with testing GPS receivers in typical Forest Service settings to help determine how well they meet the Forest Service's needs. As GPS systems are improved, MTDC will continue testing and evaluating the newest technologies to see how well they meet the Forest Service's needs.
