Abstract
In order to deeply study the characteristics and laws of downlink beam in satellite in-orbit motion, this paper proposes a multi-attitude disturbing force-GNNRL (DF-GNNRL) simulation technique based on satellite downlink beam calculation. The technique first studies the satellite in-orbit motion law and the calculation parameters of downlink beam under multi-attitude adjustment, establishes the mathematical model with corresponding arithmetic power on this basis, completes the data flow analysis of multiple models in the calculation process, further designs the coding algorithm, realizes the real-time data calculation and multi-terminal storage, builds the satellite multi-attitude DFGNNRL digital twin, and finally completes the satellite multi-attitude DF-GNNRL digital twin by means of information technology. The application of this technology can provide a strong analysis basis and data support for satellite in-orbit motion and downlink beam calculation under virtual simulation conditions.
