遥控和遥测包应用标准在航天器中的使用方法

Application Method of Telecommand and Telemetry Packet Utilization Standard in Spacecraft

对遥控和遥测包应用标准(PUS)的产生历史、应用现状以及主要特性进行了分析。针对中国航天器中遥控遥测应用层格式不统一、设备和软件无法通用等问题,探讨了在中国航天器中如何使用包应用标准。文章从遥控应用和遥测应用两方面阐述了包应用标准在中国航天器上的应用方法,着重分析了遥控遥测链路协议选择、包应用标准业务选择、遥控遥测包的传输方法等方面。使用包应用标准,将有助于进一步实现遥控遥测系统的标准化,以及航天器上设备和软件的通用化。

History,application status and main characteristics of telecommand and telemetry pack- et utilization standard （PUS） are analyzed. Aiming at the problems of inconsistent telecommand and telemetry data formats and non-universal devices and software. An application method of PUS to be used in Chinese spacecraft is discussed in terms of telecommand application and telemetry application. The selection of telecommand and telemetry data link protocol, the selection of PUS services and the transfer method of telecommand and telemetry packet are focused and discussed. Application of PUS will benefit the standardization of telecommand and telemetry system and the universal use of devices and software on board.
