本文论述星上计算机(OBC)在ADEOS(地球观测平台技术卫星)的通信与数据处理(C&DH)分系统上的应用情况。ADEOS C&DH分系统的用途是自动操作任务仪器和实现OBC的自主内务管理。OBC的工程模型已成功研制出来并顺利通过测试,测试结果证实了采用OBC自动执行和自主操作的灵活性。OBC根据地面约每周两次向卫星发出的操作程序自动操作任务仪器和总线仪器,通过监视不同设备的遥测数据自主处理事故。这些特点使得任务运营过程既简单又可靠。
This article discusses the application of On-board Computer (OBC) to the communications and data processing (C & DH) subsystem of ADEOS (Earth Observation Platform Technology Satellite). The purpose of the ADEOS C & DH subsystems is to automate the task instruments and implement OBC’s autonomous housekeeping. OBC’s engineering model has been successfully developed and successfully passed the test, the test results demonstrate the flexibility of using OBC to perform and operate autonomously. OBC automatically operates mission and bus instruments based on approximately twice-weekly operational procedures sent to satellites on the ground and processes the accident autonomously by monitoring telemetry data from different devices. These characteristics make the task operation process simple and reliable.
