Orbital transfer iteration initial value calculation method, device and equipment of DRO orbit and medium

The invention relates to an orbit transfer iteration initial value calculation method and device for a DRO orbit, equipment and a medium. The method comprises the following steps of: performing interpolation according to a point position coordinate of a DRO orbit passing through an X axis in a lunar L2 coordinate system and an initial orbit epoch, and calculating to obtain an epoch moment when the DRO orbit passes through the X axis by utilizing a DRO orbit period value; selecting a speed interpolation table according to the moon center height of the DRO orbit at the current moment and the epoch moment passing through the X axis; acquiring transfer orbit flight duration and orbit transfer speed increment from the selected speed interpolation table; determining an orbital transfer speed increment azimuth angle by using the transfer orbit flight duration and the orbital transfer speed increment, and calculating according to the orbital transfer speed increment azimuth angle and the point position coordinates pa
