GPS Technology and its Application in Agriculture Engineer

As a support technique of precision agriculture, the technology of GPS has been widely applied in agriculture engineering. The concept of GPS, the development of GPS, the constitute of GPS, the principle of its working and its main feature were introduced in this paper, its application in precision and in agriculture engineer were illustrated. By the technique we can carry out precision irrigation, no-body pilot and navigation in farm machine. With the technique being popular and application, transform will be take place in agriculture equipping and irrigation technique.
