Ran bearing its said that an independent satellite navigation system for China’s national security is very important. Without such a system, this country can not call themselves big and strong. He said, opening the field to the civil system will also help the economy.

Government recognizes the Beidou system is currently used in three of the most inaccurate satellite navigation system – the first civilian accuracy of 25 meters, after next year will launch more satellites up to 10 meters; but it also provides a unique emergency services – - SMS Service.

Military experts as the Chinese Beidou system over the past 15 years, the U.S. Navy to deny or prevent conflict in the case of trying to interfere in China’s coastal waters into the part of the effort.

The system also received the Chinese territorial disputes to those of neighboring countries with a significant tactical advantage.
