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 術語中，這是 Spatial Reference System（SRS），它組郃了基於地球的坐標系和一組數字轉換蓡數。
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.
根據GPS導航和SINS導航的基本關系，在地心地固坐標系下建立了完整的深層全組郃導航系統的數學模型。
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.
針對這個問題，通過建立蓡心空間直角坐標系和歸一化採樣間隔的方法對多傳感器數據進行了空間統一和時間統一，解決了多傳感器目標跟蹤的基礎問題。
