Abstract:	In the precision of navigational systems continues develop as rapidly as it has in the recent past there will be a time in the near future when the accuracy of star positions, to the order of 0.”1, may become one of the factors that has to considered in establishing the limitations of the systems. The basic star data for most navigational problems must e derived from sources known as fundamental star catalogues. The positions and proper motions of the stars in these catalogues, without exception, contain both random and systematic errors which, in the long run, are capable of producing a serious, progressive deterioration of the update positions. The purpose of these remarks is to establish a few guides that may be used in estimating the relative merits of a few of the more commonly used sources for star data.
