摘要
多源自主导航系统技术是新一代国家综合定位、导航与授时(Positioning,Navigation and Timing,PNT)体系下终端用户导航系统的技术发展方向。聚焦于多源信息自主感知的可检测性,分析了可检测性理论构建存在的科学技术问题,基于任务场景、运动环境以及载体动力学特征等,提出了多源自主导航系统模型表征、风险识别和可检测性量化与动态迭代优化的解决方案,为多源自主导航系统技术体系构建打下基础。
Multi-source autonomous navigation system technology is the technical development direction of end-user navigation systems under the national positioning,navigation and timing(PNT)system.The detectability of multi-source information autonomous perception is focused on,and the scientific and technical problems in constructing the detectability theory are analyzed.Based on the task scenario,motion environment,and carrier dynamics characteristics,solutions for multi-source autonomous navigation system model construction,risk identification,detectability quantification and dynamic iterative optimization are proposed,laying a solid foundation for the technology system construction of the multi-source autonomous navigation system.
