本标准包含适用于在空间数据通道上以恒定帧速率传输的固定长度数据结构的遥测传输帧的定义。 遥测传输帧为通过遥测空间数据链路传输空间采集数据提供了标准化的数据结构。 通常，数据源位于空间中，接收器位于地面上。然而，本标准也可以应用于空间到空间的遥测数据链路。 分别在以下出版物中可以找到关于本标准适用性的进一步规定和指导: - 更高层次的标准ECSS-E-ST-50，通信，其定义了与空间通信（物理到应用层）相关的所有通信层的通信协议和相关服务的原理特征，以及它们彼此之间的基本关系。 - ECSS-E-HB-50手册，通信准则，其中提供了有关这些协议的具体实施特征的信息，以便支持为空间任务的具体要求选择某种通信配置文件。 请在本标准的用户参考这些文件之前对其进行决定

This Standard contains the definition for Telemetry Transfer Frames which are fixed-length data structures, suitable for transmission at a constant frame rate on a space data channel. The Telemetry Transfer Frame provides a standardized data structure for the transmission of space-acquired data over a telemetry space data link. Usually, the source of the data is located in space and the receiver is located on the ground. However, this Standard may also be applied to space-to-space telemetry data links. Further provisions and guidance on the application of this standard can be found, respectively, in the following publications: - The higher level standard ECSS-E-ST-50, Communications, which defines the principle characteristics of communication protocols and related services for all communication layers relevant for space communication (physical- to application-layer), and their basic relationship to each other. - The handbook ECSS-E-HB-50, Communications guidelines, which provides information about specific implementation characteristics of these protocols in order to support the choice of a certain communications profile for the specific requirements of a space mission. Users of this present standard are invited to consult these documents before taking decisions on the implementation of the present one. This standard may be tailored for the specific characteristics and constraints of a space project in conformance with ECSS-S-ST-00.
