To date,the United States,Russia and the European Union have promulgated or amended legislations,presidential decrees,administrative regulations and directives concerning the issue of satellite navigation,forming a relatively comprehensive administrative and legislative system.By delineating the executive missions,operation mechanisms and procedures for the satellite navigation sectors in the respective states,such system has laid a solid foundation and provided legal guarantees for the development of their satellite navigation systems.In China,there have already been some national,state-departmental and provincial policies and regulations of similar targets,such as National Satellite Navigation Industry Mid-term and Long-term Development Plan; however,insufficiencies in the legislative and administrative system of China's satellite navigation development still exist,namely,a lack of top-level laws or regulations,arbitrariness in policies,uneven organization of the policy structure,and imbalance of policy subjects.By applying the approach of quantitative research,this article conducts a systematical summary and analysis of the regulations,laws,and political documents concerning satellite navigation in China and to explore the transformation process and diffusion of the policies,as well as the relationship between the authorities involved.In so doing,it aims at figuring out the kernel problems of the political and legislative system of the current satellite navigation in China and putting forward corresponding solutions to them,including the need for an improved system with timely top-level policies,the need for the promotion of industrial development and optimization of the policy structure,and the need for a coordinated relationship between policy subjects and a guarantee for the implementation of policies.
