摘要
分析了伪距与激光测距法时间比对的基本原理,分别从数学和几何角度详细推导了地心非旋转坐标系中伪距与激光测距法时间比对的基本计算模型,这对于实现星地之间高精度的时间同步具有重要意义。
According to the principle of the method of pseudorange and SLR time comparison, the computation model of the method of pseudorange and SLR time comparison in the non- rotating geocentric system has been derived in the angle of mathematics and geometry, so it is very important for achieving satellite-ground time synchronization in high precision.
