- Аннотация: We develop numerical ephemerides of telluric planets to compact analytical series valid over 3000BC-3000AD. The long-term planetary ephemerides DE406 are used as the source; a spectral analysis of tabulated values for the heliocentric mean longitude of every telluric planets is made. For that purpose we used our modification of the spectral analysis method which allows one to develop the tabulated values directly to Poisson series where both amplitudes and arguments of the series' terms are high-degree polynomials of time. As a result, the maximum difference between the mean longitudes of the telluric planets given by the numerical ephemerides DE406 and the new analytical series is less than 0.07 arcsec over the total time interval of 6,000 years. The number of Poisson terms in every development is less than 950.
