英文摘要： Cooperation of navigation carriers based on wireless network architecture is an important approach for navigation system to overcome the bottleneck between efficiency and investment, thus is a promising direction for the continuation of navigation theory. The innovation of this research is to apply wireless network theory into navigation technique, and the study starts from designing an all-purpose navigation carrier sensor networks (NC-NET), on which we research the key issues in networked navigation theory item-by-item. Finally, the research can form a basic theory architecture for networked navigation, which is composed of network architecture and key protocols, networked navigation scheme and related algorithms, QoS and optimization strategies. The main contents of the study include: (1) As to the navigation and localization requirement of navigation carrier, an all-purpose NC-NET protocol architecture is proposed, and related mechanisms are designed hierarchically. (2) Based on NC-NET architecture, a set of networked navigation's schemes are presented, and related algorithms are deduced in terms of state estimation and fusion. (3) QoS architecture is established based on information theories, and optimization strategy for navigation algorithms are designed based on control theories. (4) According to a specific application, the performance of NC-NET is verified by theoretical analysis and simulation, and experimental flat-form will be designed. The results of this research can provide some theoretical supports for military fields of cooperative navigation and intelligent traffic in the scenarios of GNSS-challenge or system failure, and for civil fields in terms of resource monitor, vehicle navigation, and intelligent traffic.
