Beidou vs. GPS/China vs. US: Global Navigation Satellite System
Today, four major countries: the US, EU, Russia, and China, have begun to develop new navigation systems. Currently, over 80 percent of navigation systems have been dominated by GPS, which was created by the US. By the end of December 2012, the Chinese Beidou Navigation Satellite System (BDS) started service in the Asian-Pacific Region. Beidou, Compass in Chinese, is the Chinese indigenous global navigation satellite system, which is similar to EU’s Galileo system, the US’s GPS, and Russian Glonass (Global Times 19 November 2012). China launched the first satellite for the BDS in 2000, and expected to expand its market inside of China about 70-80 percent by 2020 (China Daily 27 December 2012). Interestingly, in the middle of December, the Chinese airplane from the marine coastal guard patrolled the Diaoyu Islands without any notice by either the Japanese SDF or American military forced in suggesting that China has been using its Beidou system to operate in the East China Sea.
