针对北斗伪卫星信号引入室内并在小尺度空间下提供高精度定位的难题,如何在顾及网络建设成本的基础上提升小尺度空间的定位时效性和定位精度是未来室内定位技术中需要解决的重要一环。此处充分结合室内环境下小尺度空间的空间特征,提出一种室内节点信标辅助的北斗伪卫星载波相位差定位方法。该方法首先将传统的大范围指纹构建问题转化为指纹节点的方式,在指纹图谱的基础上提出室内节点信标的概念,通过信标节点实现小尺度空间与周围空间的连接,并对以载噪比和载波相位为基础的信标特征谱构建与处理进行了分析;然后以室内节点信标为基础给出了基于载波相位差的位置估计过程,最后结合粒子群寻优算法提出一种顾及行人特征的位置与速度空间约束下的位置搜索算法。在真实环境下的试验结果表明,通过室内节点信标的辅助在室内环境可以实现动态定位精度优于30 cm、暂停态下的定位精度优于25 cm的定位效果。正常步速运动下算法与惯性导航定位精度相当,同时相比于惯性导航方式具有更宽松的运动姿态条件。在小尺度空间下算法具有更优的适用性。

《清华大学藏战国竹简》收录的《五纪》可以说是目前出土关于天文历法与人间道德题材的唯一长篇文献,记载了有关天文历法的神话传说及诗歌祝颂,类似维柯《新科学》所谓的“诗性宇宙”“诗性天文”“诗性时历”。《五纪》以“后帝”这一上帝视角安排日、月、星、辰、岁“五纪”的周天秩序,富有神话性和仪式性,指明了与之相配的人间道德礼、义、爱、仁、中“五德”的来源,具有上古复合文化的特点。《五纪》中收录了6篇祝颂,属于“祝词系文学”,与祝宗文化关系密切,在一定程度上反映了《五纪》的行文脉络,体现了上古天文历法之书的诗体性质,为郊祀乐府之先声。
