NASA航天飞机将成为80年代及其以后年代把人和有效载荷送入地球轨道的运输工具。航天飞机飞行系统包括轨道器、外贮油箱、和两个固体火箭助推器。轨道飞行器—航天飞机的主体单元,在进入轨道火箭脱离之后就可在空间进行各种任务作业,完成任务后,返回大气层就象一个普通的商用喷气式飞机一样着陆。本文介绍了航天飞机航天电子设备,着重介绍轨道器在轨执行任务中信号处理、监视和遥测系统的功能,内容有S波段和 Ku波段射频发射链路以及有关地面站、有效载荷接口和支援设备。还讨论了其仪表系统(包括提供信息格式的能力),机载监视系统(包括专用显示器、阴极射线管和告警系统)的特点,以及存储与处理数据的方法。还简单讨论了用于各种有效载荷的轨道飞行器设备以及空间运载系统和轨道飞行器未来发展趋势。
The NASA space shuttle will be the means of transport of people and payload into Earth orbit in the 1980s and beyond. The shuttle flight system includes orbiter, external fuel tank, and two solid rocket boosters. Orbiter - The shuttle’s main unit, which is capable of performing various mission tasks in space after the orbital rocket is disengaged, returns to the atmosphere to land like an ordinary commercial jet. This article introduces the space shuttle aerospace electronics that focuses on the functions of the signal processing, monitoring and telemetry systems in orbit of the orbiter. It includes the S-band and Ku-band radio-frequency transmission links and the associated ground stations, payload interfaces and support equipment . It also discusses the characteristics of its instrumentation systems, including the ability to provide information formats, on-board surveillance systems including dedicated displays, cathode ray tube and alarm systems, and methods for storing and processing data. The discussion also briefly discusses the future development of orbital aircraft equipment for various payloads as well as space delivery systems and orbital aircraft.
