To an accuracy of 10 to the -13th, the equation of motion of a test particle and the average first-order derivatives of its orbital elements were derived under the geocentric n-body metric and under the Kerr metric. On this basis, the general relativistic effects of a spherical earth, and the rotation and the J2 term of the earth on the orbits of artificial satellites are analyzed. It is concuded that the longitude of the ascending node, the argument of pericenter and the mean anomaly are subject to secular and periodic perturbations and that these relativistic effects should be taken into account when determining satellite orbits on long arcs in dynamical geodesy.
