How GPS Machine Control WorksGPS machine control systems all have many things in common. Scrapers, excavators, blades, and even tractors all must use the same basic concept when utilizing GPS. All GPS systems receive signals from satellites in the sky broadcasting positions; a base station on your job site picks up these signals. The base station "learns" where it is and "locks" in its position. Once the base knows where it is, it can read the GPS signals and send the working machines the positional error corrections. The computers onboard the moving machines receive these messages via radio or cell phone signals over 20 times a second, as their location changes, and generate coordinates for the computer to compare to grade. While thinking about GPS Machine Control, it helps to view the machines as rovers with blades on them. The machine is attempting to attain the specified grades, while the rover is trying to determine deviance of the blade from that grade. Imagine doing both at the same time and then having the computer-driven movement of the blade fix the difference. This incredible precision explains why GPS machine control has become so popular -- all off the grading work is done from the same reference point in space, in exact accordance to the plans of the job, making the work faster and ultra-accurate.
