Scientific paper
An outline of the currently available accuracies of stellar positions in a fundamental or absolute system is given. From what can be expected from ground based observational techniques in the near future, it appears that with the stated accuracies from Professor Lacroute's project in the Spacelab version of 0.001 arc sec for absolute positions and parallaxes, it is possible to obtain significant improvements in the fundamental reference system and its extension to fainter objects.
