AI Technical Summary
Technical Problem
In satellite constellation networks, data transmission delays occur due to fluctuating communication capacities between satellites and ground stations, especially when using optical or radio-wave links, leading to increased latency and inefficiencies in data downlinking.
Method used
A control station that determines optimal communication paths and ground stations based on line quality and fault information to balance data transmission across multiple communication lines, minimizing transmission delays by adjusting the destination ground stations and routes.
Benefits of technology
The control station effectively manages communication lines to suppress data transmission delays and optimize data downlinking, ensuring efficient utilization of satellite-to-ground station links.

Abstract
The control station (3) controls a constellation network that includes a plurality of satellite stations (1) and a plurality of ground stations (2), each mounted on an orbiting satellite, and in which some of the plurality of satellite stations (1) communicate directly with the ground stations (2). The control station (3) includes a destination control unit (34) that determines, based on the line quality of the communication line (12) used by the satellite station (1) for direct communication with the ground stations (2), the destination ground station that is the ground station (2) with which each of the plurality of satellite stations (1) communicates when transmitting downlink data.
