Zusammenfassung
The generalized Kepler equation is a transcendental non-linear equation which appears in the zonal problem of the artificial satellite theory when the Krylov-Bogoliubov-Mitropolsky method is employed. In this work, the Lie-Deprit method is used to apply Lagrange's inversion theorem in order to solve the generalized Kepler equation. For small eccentricities, the analytical approximate solution yields similarly accurate results to numerical methods. For the rest of eccentricities, we discuss the applicability of this approximation as an initial guess in the numerical method used to solve the generalized Kepler equation.
