The rotating reference frame and the precession of the equinoxes

In this paper, angular frequency of a rotating reference frame is derived, where a given body orbiting and rotating around a fixed axis describes a periodical rosette path completing a periodical “circular motion”. Thus, by the analogy between a rotating frame of reference and the whole Solar System, angular frequency and period of a possible planetary circular motion are calculated. For the Earth's case, the circular period is calculated from motion of the orbit by the rotation effect, together with the advancing caused by the apsidal precession, which results the same amount than the period of precession of the equinoxes. This coincidence could provide an alternative explanation for this observed effect.
