全球星有限公司正在开发“全球星”系统。该系统将利用48颗位于低轨道的卫星创建一个世界范围的移动通信系统,这一点与戈尔副总统所展望的“全球信息高速公路”是一致的。作为由一个新成立组织开发的庞大的长期商用系统,“全球星”为探索高效率的卫星指令和控制的新方案提供了一个绝好机会。发展中的设计和运行方案不会受到现有的物理和组织结构的阻碍。这一计划的确是“从零开始的”。本文讨论了“全球星”系统并提出了工程实现方案、系统设计抉择以及运行方案,这就对卫星、地面系统和测控人员提出了综合要求。针对卫星星座的运行管理,应用了从以往的飞行任务中吸取的经验,组织机构间的壁垒已被打破,横跨各个任务部门的合作关系业已形成,新的运行方案已开发出来。这篇论文概要总结了这些工程方法和思想在未来不同等级飞行任务中的适用性。
Global Star Co., Ltd. is developing “Global Star ” system. The system will use 48 low-orbiting satellites to create a worldwide mobile communications system that is consistent with Vice President Gore’s vision of a “global information superhighway.” As a massive long-term commercial system developed by a newly formed organization, Global Star offers an excellent opportunity to explore new options for efficient satellite command and control. Developing design and operational scenarios are not impeded by existing physical and organizational structures. This plan is indeed “from scratch ”. This article discusses the “Global Star” system and presents engineering solutions, system design choices, and operational scenarios that put forward comprehensive requirements for satellites, terrestrial systems, and monitoring and control personnel. In view of the operational management of satellite constellations, the lessons learned from past missions were applied, the barriers between organizations were broken, and the cooperative relations across various mission departments had been formed and new operational plans were developed. This essay summarizes the applicability of these engineering methods and ideas in different levels of future missions.
