ChinaMil Net recently republished an article by PLA Daily introducing the Bei Dou System – China’s self-developed GPS system. The report is based on information provided by Dr. Qi Faren, who is the former Chief Architect and Designer of the Chinese Manned Space Operations Project, director of the Aerospace College of Beijing University of Aeronautics and Astronautics, an Academician for the International Academy of Astronautics (IAA), and an Academician for the Chinese Academy of Engineering. The report covered the architecture of the Bei Dou System, the satellite launching illustration, and a comparison of the four primary GPS systems in the world. The Bei Dou System is entirely based on Chinese intellectual property. By 2012, the system will cover the Asia-Pacific areas. Global coverage with more than 30 satellites is expected by 2020. The bi-directional short messaging capability is believed to be superior to the unidirectional US GPS system.
