Automatic guidance based on GPS is a rapidly expanding technology in the area of precision agriculture. Its adoption is fueled by a quick return on investment, ease of operation and installation, as well as the availability of lower-cost system options. This report covers the history of the development of vehicle guidance from the early days of guidance to current and future applications with a focus on GPS-based automatic guidance. It also reviews GPS basics, the different correction sources typically used in agriculture, as well as future developments we can expect in Global Navigation Satellite Systems.
