Abstract

With the development of the transportation industry, the effective guidance of aircraft in an emergency to prevent catastrophic accidents remains one of the top safety concerns. Undoubtedly, operational status data of the aircraft play an important role in the judgment and command of the Operational Control Center (OCC). However, how to transmit various operational status data from abnormal aircraft back to the OCC in an emergency is still an open problem. In this paper, we propose a novel Telemetry, Tracking, and Command (TT&C) architecture named Collaborative TT&C (CoTT&C) based on mega-constellation to solve such a problem. CoTT&C allows each satellite to help the abnormal aircraft by sharing TT&C resources when needed, realizing real-time and reliable aeronautical communication in an emergency. Specifically, we design a dynamic resource sharing mechanism for CoTT&C and model the mechanism as a single-leader-multi-follower Stackelberg game. Further, we give an unique Nash Equilibrium (NE) of the game as a closed form. Simulation results demonstrate that the proposed resource sharing mechanism is effective, incentive compatible, fair, and reciprocal. We hope that our findings can shed some light for future research on aeronautical communications in an emergency.
基于巨型星群的 TT&C 资源共享:在紧急情况下保持可靠的航空通信
随着交通运输业的发展,如何在紧急情况下有效引导飞机以防止灾难性事故的发生,仍然是人们最关心的安全问题之一。毫无疑问,飞机的运行状态数据对运行控制中心(OCC)的判断和指挥起着重要作用。然而,如何在紧急情况下将异常飞机的各种运行状态数据传输回运行控制中心仍是一个悬而未决的问题。本文提出了一种基于超大型星座的新型遥测、跟踪和指挥(TT&C)架构,名为协同 TT&C(CoTT&C),以解决这一问题。CoTT&C 允许每颗卫星在需要时通过共享 TT&C 资源来帮助异常飞机,从而在紧急情况下实现实时可靠的航空通信。具体而言,我们为 CoTT&C 设计了一种动态资源共享机制,并将该机制建模为单领导者-多追随者的 Stackelberg 博弈。此外,我们还给出了博弈的唯一纳什均衡(NE)闭合形式。模拟结果表明,所提出的资源共享机制是有效的、激励相容的、公平的和互惠的。我们希望我们的研究结果能为今后的应急航空通信研究提供一些启示。
