Scientific paper

Two FORTRAN programs are presented which can be used in numerical methods of satellite geodesy for the integration of both the equations of motion and the variational equations. It is shown that the ML4A solution represents the Lageos orbit on 5-day arcs with the same accuracy as the set of GEM-L2 harmonics. A similar comparison is made for the computation of the Starlette orbit using GEM-9 harmonics and the LPM-1A solution. The advantage of using the ML4A over the GEM-2 is confirmed; the use of the ML4A leads to a 50-percent decrease in computer time.
