In this paper an orbit computation program for artificial satellites is presented. This program is operational and it has already been used to compute the orbits of several satellites.After an introductory discussion on the subject of artificial satellite orbit computations, the features of this program are thoroughly explained. In order to achieve the representation of the orbital elements over short intervals of time a drag-free perturbation theory coupled with a differential correction procedure is used, while the long range behavior is obtained empirically. The empirical treatment of the non-gravitational effects upon the satellite motion seems to be very satisfactory. Numerical analysis procedures supporting this treatment and experience gained in using our program are also objects of discussion.

At its Liège meeting, in July 1963, the Executive Committee of the Union voted to hold this Joint Discussion as a small homage to the memory of Professor Struve. I do not need to stress why the subject of ‘Close Binaries’ was chosen as we all know that it was closer to Professor Struve’s heart than any of the other ones in which he divided his broad astronomical interest.Mrs Mary Struve has written to me the kind letter I am going to read, a letter which summarizes so clearly how much Professor Struve would have appreciated this kind of homage.
