Abstract

The Johns Hopkins University Applied Physics Laboratory (APL) has developed numerous spacecraft for national security and civilian space applications that have used varied flight computers and ground control systems. On missions that have utilized different ground control systems, the command and telemetry (C&T) database development has been unique to the specific mission. On missions that have utilized a common ground control system, APL has leveraged a limited extent of commonality in the development of the C&T databases, which has shown promise in development, schedule, and cost efficiency and has improved the quality of the early C&T database deliveries. On its recent Radiation Belt Storm Probes mission (RBSP), APL developed a set of C&T tools to tackle the challenge of developing a common C&T database across multiple satellites, over full mission life cycles, that minimizes coupling with the core ground control system such that the use across different ground systems is maximized. This paper discusses the specific approach taken in evaluating the C&T database development for APL's past missions and the shortfalls that were encountered. Lessons learned were evaluated and decisions were made in implementing the RBSP C&T databases. The tool development is briefly discussed with an emphasis on the engineering use during satellite subsystem development. Recent successes during the testing are also presented. Finally, plans are described for continued improvement to the approach and tools for subsequent APL spacecraft so that the C&T database can be ported to other missions of interest.
开发独立于地面控制系统的命令和遥测处理接口
约翰霍普金斯大学应用物理实验室(APL)已经为国家安全和民用空间应用开发了许多航天器,这些航天器使用了各种飞行计算机和地面控制系统。在使用不同地面控制系统的任务中,指挥和遥测(C&T)数据库的发展对具体任务来说是独一无二的。在使用公共地面控制系统的任务中,APL在C&T数据库的开发中利用了有限范围的通用性,这在开发、进度和成本效率方面显示出了希望,并提高了早期C&T数据库交付的质量。在其最近的辐射带风暴探测任务(RBSP)中,APL开发了一套C&T工具,以解决在整个任务生命周期内跨多颗卫星开发通用C&T数据库的挑战,从而最大限度地减少与核心地面控制系统的耦合,从而最大限度地利用不同的地面系统。本文讨论了在评估APL过去任务的C&T数据库开发时所采取的具体方法以及所遇到的不足。在实施RBSP C&T数据库时,评估了经验教训并作出了决定。简要讨论了工具的开发,重点介绍了卫星分系统开发中的工程应用。本文还介绍了最近在测试过程中取得的成功。最后,描述了继续改进后续APL航天器的方法和工具的计划,以便C&T数据库可以移植到其他感兴趣的任务中。
