卫星导航技术发展向何处去
摘要
New progress of navigation and positioning technology, especially satellite navigation and positioning technology is reviewed in this paper. Development trend and direction of satellite navigation technology after GPS is discussed. Compatibility and interoperability of multi-mode satellite navigation system, integration and complementarity of satellite navigation with ground mobile network, and the integration of navigation and communication technology are introduced respectively in the first place. Then the inbound satellite positioning and communication system and bi-directional satellite positioning communication system are proposed. Finally, the possibility of the integration of navigation signal and function into the communication link is looked into the future.
