本立场文件的主要重点是审查ITRF合并所必需的共址站点的现状。同一地点的定义是根据不同技术的大地测量标记或仪器参考点之间的距离和连接它们的局部联系的准确性给出的。总结了目前共置站点的分布和质量。鉴于空间大地测量技术和建模测量精度的提高，1毫米或更高的精度应该是所有新的地方测量的目标。此外，带有完整方差-协方差信息的SINEX文件现在是强制性的。
The main focus of this position paper is to review the current status of the co-location sites, necessary for ITRF combination. The definition of a co-location site is given in terms of distance between geodetic markers or instrument reference points of different techniques and accuracy of the local ties connecting them. Distribution and quality of the current co-location site are summarized. Given the precision increase of the measurement of the space geodesy techniques and modelling, 1 mm precision or better should be the goal of all new local tie surveys. Moreover, SINEX files with full variance-covariance information is now mandatory.
