METHOD OF DETERMINING THE SEQUENCE OF FLIGHTS BETWEEN OBJECTS OF SPACE DEBRIS WITH A SIGNIFICANT DIFFERENCE IN THE LONGITUDE OF THE ASCENDING NODE OF THEIR ORBITS Russian patent published in 2019 - IPC B64G1/24 B64G1/26 

FIELD: astronautics.

SUBSTANCE: invention relates to spatial maneuvers of spacecrafts in non-central gravitational field of Earth when approaching space debris objects (SDO). SDO overflight scheme is selected on the basis of a portrait of the evolution of deviations of longitudes of ascending nodes of the SDO orbits, wherein these deviations are determined relative to the orbit of one of SDO. If the given portrait has the form of quasi-parallel lines, then a serial circuit is used, transferring the active spacecraft into a waiting orbit with a modified precession speed of the node line. At repeated intersection of specified lines on portrait diagonal circuit is used – when orbit of next withdrawn SDO serves orbit of spacecraft waiting to reach next SDO. After selecting SDO overflight scheme, parameters of spacecraft maneuvers are determined using some three nested iterative procedures.

EFFECT: reduced expenditures of total characteristic speed of spacecraft for overflight of group of SDO or at specified costs increase in number of available SDO.
