Beidou system poised to spread wings

China's Beidou navigation satellite system, whose positioning accuracy will reach 2.5 meters by 2020, will soon provide services to more countries.

The National Administration of Surveying, Mapping and Geoinformation said China will cooperate with several countries, including Mexico, Israel and Sweden, to improve establishment of the Beidou system and geoinformation database.

International cooperation and establishing monitoring stations in foreign countries are essential for improving the accuracy of the system, said Li Pengde, the administration's deputy director.
