论文摘要
最近由大型星座和高级有效载荷代表的高级低地球轨道（LEO）卫星网络为使高质量的Internet连接到地球上的任何地方提供了巨大的承诺。但是，传统的基于卫星操作的方法无法满足LEO卫星的实时，可靠和弹性操作的紧迫要求。考虑到卫星平台上的高级KA波段和光学通信有效负载，基于多层卫星网络提出了新方案。提出的方案可以通过卫星网络的不同层，由LEO，中级轨道（MEO）和地静止（GEO）卫星组成，可以通过不同层的卫星网络来实现关键的遥控和遥测任务的有效且有弹性的消息传输。该方案在24小时的卫星任务中进行了评估，与传统操作方法相比，该方案表现出卓越的性能提高。
Recently advanced low-Earth-orbit (LEO) satellite networks represented by large constellations and advanced payloads provide great promises for enabling high-quality Internet connectivity to any place on Earth. However, the traditional access-based approach to satellite operations cannot meet the pressing requirements of real-time, reliable, and resilient operations for LEO satellites. A new scheme is proposed based on multi-layer satellite networking considering the advanced Ka-band and optical communications payloads on a satellite platform. The proposed scheme can enable efficient and resilient message transmissions for critical telecommand and telemetry missions through different layers of satellite networks, which consist of LEO, medium-Earth-orbit (MEO), and geostationary (GEO) satellites. The proposed scheme is evaluated in a 24-hr satellite mission and shows superior performance improvements compared to the traditional operations approach.
