摘要
根据下行L波段轨道法时间比对的基本原理,详细推导了其在地心非旋转坐标系中的基本计算模型,并以静止地球同步轨道卫星为例,分析了该计算模型中的距离改正项时延对星地间相对钟差的影响量级。
According to the principle of the method of down L-wave-band orbit time comparison, its computation model in the non-rotating geocentric system has been deduced. Taking the geostationary satellite for example, the quantity grade of the influence of every item in the distance correction time delay of the computation model to the relative station-station time difference has been analyzed.
