【摘要】：綜合定位導(dǎo)航授時是后GNSS(全球衛(wèi)星導(dǎo)航系統(tǒng))發(fā)展的必然趨勢。本文側(cè)重梳理微PNT發(fā)展需求和發(fā)展現(xiàn)狀,分析與之關(guān)聯(lián)的核心關(guān)鍵技術(shù),論述綜合PNT與微PNT的關(guān)系。強調(diào)綜合PNT需要大量基礎(chǔ)設(shè)施投入與建設(shè),而微PNT側(cè)重高技術(shù)傳感器的集成應(yīng)用。與現(xiàn)有文獻(xiàn)思路不同的是,我們認(rèn)為,為了實現(xiàn)各類傳感器PNT輸出結(jié)果的坐標(biāo)基準(zhǔn)統(tǒng)一和時間尺度一致,微PNT應(yīng)包含多模GNSS和芯片級慣性導(dǎo)航和芯片級原子鐘等定位定時組件,微PNT強調(diào)小型化、個性化、組合化服務(wù)終端;微PNT除各PNT組件的小型化外,還包括各組件的深度集成,各類數(shù)據(jù)的自適應(yīng)融合和各組件的自主標(biāo)校;當(dāng)然,微PNT也強調(diào)各傳感器信息的時空基準(zhǔn)的統(tǒng)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.
