Method of energy estimation of interorbital transfers for LEO spacecraft on-orbit servicing

The problem of planning the circumnavigation of space objects requiring servicing is considered. It is assumed that system of base stations for servicing the given array of the satellites on different LEO orbits has been deployed. For a fixed time it is needed to flyby each satellite which requires servicing. The servicing is conducted using the detachable orbital modules (OM) from the base stations (BS). Basing on the longitude of ascending node deviation portrait for all serviceable satellites and base stations it is defined which OM should transfer to the vicinity of which satellite in order to have the lowest Delta-V budget. © 2017 Univelt Inc.
