摘要
处理光传播时延观测模型时，一般有两种作法，即在BRS或GRS中处理，但这两种结果，进行参考系间的时延转换时并不严格相等。本文对这一问题作了仔细分析，指出总理 的根源在于他们使用的时延转换公式并不精确，应以修正，文中推导出这些改正项，并用新的时延转换公式严格证明了在PN1精度下与时延有关的观测模型在两类参考系中的等价性。
hile dealing with the light propagation m0dels in Barycentric Reference System andGeocentric Reference System, We find 0ut that the results are different when the time - delaytrasformation formulae between these tw0 frames are used[l'2j. Thes paper has discussed thisproblem in details, and points 0ut why the widely used time - delay formula is not precise.The correcti0n terms have been derived and the equivalence of the two light propagationmodels has been under the new transformation f0rmulae has been pr0ved.
