earth coordinate system

基本解释

In the terminology of the Spatial Extender, this is the Spatial Reference System (SRS), a combination of an earth-based coordinate system and a set of numeric conversion parameters.
在 Spatial Extender 术语中，这是 Spatial Reference System（SRS），它组合了基于地球的坐标系和一组数字转换参数。
According to the basic theory of GPS navigation and SINS navigation, the comprehensive mathematic models of integrate navigation system is built under Earth Center Fixed coordinate system.
根据GPS导航和SINS导航的基本关系，在地心地固坐标系下建立了完整的深层全组合导航系统的数学模型。
Aiming at this problem, the equations for spatial-temporal data unification are presented, which are got by building referenced earth center space coordinate system and unifying sampling interval.
针对这个问题，通过建立参心空间直角坐标系和归一化采样间隔的方法对多传感器数据进行了空间统一和时间统一，解决了多传感器目标跟踪的基础问题。
