Digital Twin Satellite Internet: Architecture and Key Technologies

Abstract

A digital twin satellite internet (DTSI) architecture was proposed, which provided support for the whole life cycle of satellite internet through the three-dimensional closed-loop mechanism of parallel twin, security endogenous and intelligent evolution.Then, the key problems and technologies of DTSI were discussed.Aiming at the complex and changeable satellite internet system, a standardized model processing and generation method based on mechanism and data driving was proposed.In the face of the data torrent formed by massive information and uneven distribution, a pool computing-storage strategy of three-level diversion strategy was proposed.In order to achieved high fi delity with the characteristics of the actual system, an intelligent orchestration and distributed heterogeneous processing platform was designed to classifi ed and quickly calculated diff erent models and events.In order to achieved high fi delity with the characteristics of the actual system, an intelligent orchestration and distributed heterogeneous processing platform was designed to classifi ed and quickly calculated diff erent models and events, the satellite internet twin cycle evolution system of observation-orientationdecision-act was formed, so as to realized the stable development of the whole life cycle of satellite internet.
