中国北斗：大国重器（英文）

　　The Beidou navigation satellite system （BDS）， one of China's three most famous trademarks， has become another Chinese business card that has entered the international arena after high-speed railway and nuclear power. It is a major achievement of scientific and technological development and innovation since the country started reform and opening up.This is an authoritative book that comprehensively， systematically and scientifically introduces the BDS and its application， with the aim to let the international community better understand China's technological innovation capability and achievements embodied in the system， and to provide the world with authoritative answers to the questions or doubts about BDS.

　　袁树友（Yuan Shuyou），chief editor of the book， has been engaged in teaching， research and management in the field of surveying，mapping and navigation since he graduated from Zhengzhou Institute of Surveying and Mapping. He used to serve as a technician，teacher， vice chairman of the Chinese Society for Geodesy， Photogrammetry and Cartography， and commander-in-chief of the operation control and application system of BDS.He has won the first prize of National Science and Technology Progress Award and many other awards. He has organized the compilation of a number of professional books and published more than 40 research papers.
