【摘要】：综合定位导航授时是后GNSS(全球卫星导航系统)发展的必然趋势。本文侧重梳理微PNT发展需求和发展现状,分析与之关联的核心关键技术,论述综合PNT与微PNT的关系。强调综合PNT需要大量基础设施投入与建设,而微PNT侧重高技术传感器的集成应用。与现有文献思路不同的是,我们认为,为了实现各类传感器PNT输出结果的坐标基准统一和时间尺度一致,微PNT应包含多模GNSS和芯片级惯性导航和芯片级原子钟等定位定时组件,微PNT强调小型化、个性化、组合化服务终端;微PNT除各PNT组件的小型化外,还包括各组件的深度集成,各类数据的自适应融合和各组件的自主标校;当然,微PNT也强调各传感器信息的时空基准的统一。
[Abstract]:Integrated positioning and navigation timing is the inevitable trend of post-GNSS development. This paper focuses on combing the development needs and status quo of micro-PNT, analyzing the key technologies associated with it, and discussing the relationship between integrated PNT and micro-PNT. It emphasizes that integrated PNT requires a large amount of infrastructure investment and construction, while micro-PNT focuses on high-tech sensors. Different from the existing literature, we believe that in order to achieve uniform coordinate and time scales of PNT outputs from all kinds of sensors, micro-PNT should include multi-mode GNSS, chip-level inertial navigation and chip-level atomic clock and other positioning and timing components. Micro-PNT emphasizes miniaturization, personalization and integration of service terminals. In addition to the miniaturization of each PNT component, it also includes the deep integration of each component, the adaptive fusion of all kinds of data and the independent calibration of each component. Of course, the micro-PNT also emphasizes the unification of the space-time datum of each sensor information.
