摘要

用于计算TAI的时间链路网络总是被选择为允许唯一解，即不使用任何冗余。在目前的情况下，许多链路可以用两种或两种以上的技术来计算(主要是TW和GPS)，并且TW网络本身是高度冗余的。此外，这两个测量值的协方差矩阵现在可以以足够的不确定性确定，因此使用所有可用信息并使用可用的冗余网络计算TAI链路是有意义的。在本文中，我们考察了在这一目标中使用的形式主义和使用这种程序的后果

Redundancy and correlations in TAI time links

The network of time links for the computation of TAI has always be chosen such as to allow a unique solution, i.e. not using any redundancy. In the present situation, many links can be computed with two or more techniques (mostly TW and GPS) and the TW network itself is highly redundant. In addition, the covariance matrix for the measurements from these two may now be determined with adequate uncertainty, so that it makes sense to use all the available information and to compute TAI links using the available redundant network. In the paper, we examine the formalism to be used in this aim and the consequences of using such a procedure
