China: China is planning to expand its homegrown Beidou navigation system by 2020 and make it accurate to within centimeters. The Chinese system has 16 satellites serving the Asia-Pacific so far and the number is expected to grow to 30 by 2020.

Currently the system can reach an error margin as low as 5 meters in trials and can be further improved to within centimeters to compete with the dominant US GPS, officials said.

The navigation system has been providing accurate and stable services to Asia-Pacific users since China launched it a year ago and other countries in Asia are welcome to use it, said Ran Chengqi, director of the China Satellite Navigation Office.
