An unmanned tractor equipped with a vegetable transplanter moves ahead in a field in Tawan village in Wuzhong city, Ningxia Hui autonomous region. An antenna and receiver sit atop the tractor. Once a plowing path has been entered via the antenna, the machine will follow the route precisely, deviating less than three centimeters per kilometer, April 17, 2018. [Photo/Xinhua]

Yihe Agricultural Machinery Operation Service Co Ltd in the city purchased seven Beidou Satellite Navigation System sets for its agricultural machinery over two years. The navigation system enables a tractor to plow with great accuracy, preventing mis-seeding and reseeding. It not only cuts farmers' workload by nearly half, but greatly improves land use and production output.
