摘要

随着航天技术发展与卫星互联网建设推进，卫星应用日益广泛，卫星边缘协同计算需求也随之增长。卫星边缘计算可下沉数据处理与任务执行，缓解星地传输压力，提升系统响应速度与可靠性，但低轨卫星边缘计算仍面临星地网络中断、星间连接弱、单粒子翻转及节点故障等挑战。针对以上问题，提出一种轻量化、高可靠的卫星边缘协同计算架构，通过研究异构资源适配、分布式协同等关键技术，为卫星智能化应用提供支撑，并助力卫星互联网产业发展。

Abstract

With the development of aerospace technology and the advancement of satellite Internet construction

satellite applications have become increasingly widespread

and the demand for satellite edge collaborative computing has grown. Satellite edge computing can sink data processing and task execution

alleviate the pressure of satellite-ground transmission

and improve the response speed and reliability of the system. However

low-orbit satellite edge computing faces challenges such as satellite-ground network interruption

weak inter-satellite connections

single event upset

and satellite node failure. This paper proposes a lightweight and highly reliable satellite edge collaborative computing architecture

studies key technologies such as heterogeneous resource adaptation and distributed collaboration

to provide support for satellite intelligent applications

and facilitate the development of the satellite Internet industry.
