OPTIMUM TRAJECTORY AND GNC ISSUES FOR LOW THRUST TRANSFER OF SATELLITE FORMATIONS

摘要

This paper focuses on the problematic associated to the interplanetary transfer of a collection of satellites and specifically on their transfer to a collinear Libration point and to HETO (Heliocentric Earth Trailing Orbit). These scenarios impose a treatment combining trajectory optimisation concepts with those related to the guidance, estimation and control of the relative state vector between the satellites composing the formation. Results for both transfer examples are also provided herein.
