System and method for supporting large dynamic inter-satellite link establishment

Abstract

The invention discloses a system and method for supporting large dynamic inter-satellite link establishment, and the system comprises a ground management and control system, a high-orbit satellite inter-satellite control unit, a high-orbit satellite antenna unit, a low-orbit satellite inter-satellite control unit, and a low-orbit satellite antenna unit, and dynamically adjusts the link establishment direction through a large Doppler frequency offset compensation method based on orbit compensation. The Doppler frequency offset effect generated when the satellite moves at a high speed and the extremely high time delay in the transmission process due to the ultra-long distance are solved, and communication time slot alignment and frequency capture are carried out timely and accurately during satellite interaction.
