Abstract

In order to ensure the stable operation of the inter-satellite link network of navigation satellites, it is necessary to improve the monitoring and management capabilities of the navigation ground system for the inter-satellite link. In this paper, an inter-satellite link situational awareness system based on telemetry data is proposed and constructed. Aiming at the insufficient monitoring ability of the ground system for the inter-satellite link network status perception delay and the insufficient prediction ability of future network trends, the telemetry information extraction is carried out. output network status indicators. The grayscale prediction algorithm is used to predict the situation of various state indicators of the inter-satellite link network. The final result shows that the correct rate of telemetry count prediction difference within three in the state reaches 84.62%. It can effectively sense the status of future satellites and deal with the abnormal status of the inter-satellite link network in combination with other systems.
