“Aerospace strategy” has been always the vial component of China’s integrated national development strategy. No matter in terms of global strategy or the calculus of national interests, Beijing realizes that competing to dominate aerospace interests becomes a key role in maintaining national security and vial interests to great powers in the world. Thus, “satellite navigation”, with great applied values in the facets of politics, economics, military, technology and national strategy, is of great significance to safeguard national interests. Concurrently, there are four emerging satellite position systems, the GPS developed by the US, the GLONASS by Russia, the Galileo by Europe and the Bei Dou Satellite Navigation System by China, which respectively possess its own advantages and disadvantages. Therefore, the purpose of this study is to review and explore the capabilities of Chin’s Bei Dou satellite from the facets of politics, economics, military and technology. Then an assessment will be made on its impact to ROC’s national security. The study finds that China is advancing its politics, economics, military and technology interests and seeking to become a globally influential great power in the international arena after examining the strategic implications of China’s developing Bei Dou System and the assessment made on Bei Dou’s capabilities.
