Abstract

The invention discloses a multi-protocol-level satellite device digital twin and a performance simulation method thereof. A system engineering method based on a model is adopted, the defects of satellite device digital twinborn design and performance simulation methods in the prior art are overcome, the performance simulation method combining the satellite network and the link hierarchy is designed from the perspective of meeting the service requirements of users, and the performance of the satellite device is simulated based on the feedback efficiency of a ground management and control center. And an optimization result and an analysis suggestion are provided for the resource capability design of each level of the satellite load.

Description

technical field [0001] The invention relates to the technical field of system engineering, in particular to a multi-protocol level satellite device digital twin and a performance simulation method thereof. Background technique [0002] With the development of information technology, the entire world in the future will generate a digital twin virtual world based on the physical world. People in the physical world, people and things, and things and things can transmit information and intelligence through the digital world. The twin virtual world is the simulation and prediction of the physical world, which accurately reflects and predicts the real state of the physical world. The digital twin of the satellite device is a part of the future digital twin virtual world, which provides information interaction simulation means for the real satellite device in the physical world, and can realize the drive of the physical world through the prediction of the future. [0003] The exis...
