Summary

During the 1968 European geodetic observing program organized jointly by the Centre National d'Etudes Spatiales, France, and the Smithsonian Astrophysical Observatory, United States, a large number of simultaneous or quasi-simultaneous laser and optical observations were collected. Particular attention has been given to the interpolation necessary to make observations exactly simultaneous. More than 2000 independent relations have thus been obtained, linking 9 station positions. The resulting relative coordinates of these stations are compared with other determinations.
