The orbit error due to solar radiation showsalso the characteristic of a sine wave with increasing amplitude, with the orbital period asnatural frequency. Compared to the LEO orbit, the perturbation of the MEO orbit has a lowerfrequency, but is faster increasing in amplitude, as can be seen in the figures. Table 4-13indicates the RMS error for different prediction periods and satellite orbits.R. Wolf Page 51
