摘要

摘要: 室内外无缝定位分为室内定位和室外定位两个独立部分.室内定位通常选取(0,0,0)作为初始地磁点的坐标,然而这一坐标会随着实验者的改变或者实验场地的变换而更换,不具备普适性.全球卫星导航系统(GNSS)虽然不能进行室内定位,但在室外定位出的地心地固坐标是唯一的,不发生改变.本文选取GNSS在室内外无缝定位过渡点的地心地固坐标点作为初始点,室内定位坐标系同样使用地心地固,可以有效解决室内外无缝定位的坐标兼容性问题,具有更广泛的作用.

Abstract: Indoor and outdoor seamless positioning is divided into two independent parts: indoor positioning and outdoor positioning. Indoor positioning usually selects (0,0,0) as the coordinate of the initial geomagnetic point, but this coordinate will be changed with the change of the experimenter or the change of the experimental site, which is not universal. Although GNSS cannot be positioned indoors, the geocentric fixed coordinates located outdoors with GNSS are unique and do not change. In this paper, the geocentric solid coordinate point of GNSS seamless positioning transition point indoors and outdoors is selected as the initial point. Geocentric solid is also used in the indoor positioning coordinate system, which can effectively solve the coordinate compatibility problem of seamless positioning indoors and outdoors and has a broader role.
