摘要:

小型卫星系统使导航、通信、遥感和民用和军用科学研究等全新类型的任务成为可能。由于单个航天器受到尺寸、质量和功率限制的限制,大规模生产的小型卫星组成的大型星座或集群可用于许多科学任务,如重力测绘、跟踪森林火灾、寻找水资源等。小型卫星星座通过用几个非常有能力的航天器取代单一资产,为新的应用打开了大门,从而促进了创新应用。随着自主程度的提高,将需要远程通信网络来实现航天器之间的通信。这些天基网络将需要配置和维护动态路由,管理中间结点,并重新配置自己,以实现任务目标。因此,当卫星编队飞行时,星间通信是一个关键方面。在本文中,我们提出了各种研究正在进行的小卫星社区实现基于开放系统互连(OSI)模型的卫星间通信。本文还回顾了适用于OSI模型前三层的各种设计参数,即,物理层、数据链路层和网络层。根据调查,我们还提出了一个全面的设计参数列表,用于实现多个小卫星任务的卫星间通信。具体议题包括针对小型卫星系统所面临的一些挑战提出的解决方案,利用小型卫星网络开展业务,以及涉及编队飞行方面的小型卫星任务的一些实例。

英文摘要:

Small satellite systems enable whole new class of missions for navigation, communications, remote sensing and scientific research for both civilian and military purposes. As individual spacecraft are limited by the size, mass and power constraints, mass-produced small satellites in large constellations or clusters could be useful in many science missions such as gravity mapping, tracking of forest fires, finding water resources, etc. Constellation of satellites provide improved spatial and temporal resolution of the target. Small satellite constellations contribute innovative applications by replacing a single asset with several very capable spacecraft which opens the door to new applications. With increasing levels of autonomy, there will be a need for remote communication networks to enable communication between spacecraft. These space based networks will need to configure and maintain dynamic routes, manage intermediate nodes, and reconfigure themselves to achieve mission objectives. Hence, inter-satellite communication is a key aspect when satellites fly in formation. In this paper, we present the various researches being conducted in the small satellite community for implementing inter-satellite communications based on the Open System Interconnection (OSI) model. This paper also reviews the various design parameters applicable to the first three layers of the OSI model, i.e., physical, data link and network layer. Based on the survey, we also present a comprehensive list of design parameters useful for achieving inter-satellite communications for multiple small satellite missions. Specific topics include proposed solutions for some of the challenges faced by small satellite systems, enabling operations using a network of small satellites, and some examples of small satellite missions involving formation flying aspects.
