这项工作的范围是制定一个标准，用于处理由星载全球导航卫星系统反射计（GNSS-R）任务产生的数据和元数据内容，该任务使用GNSS信号作为机会信号，如a？IEEE SA星载GNSS-R工作组:场景研究。A.特别是，本标准将提供一种方法来描述: a） 分配给GNSS-R数据和产品的术语，如产品级别。 b） 数据的结构和内容。这包括但不限于测量单位、数据组织、数据描述、数据编码和数据存储格式。 c） 元数据。这包括但不限于元数据、应用于数据的方法和算法、与算法相关的参数、引文信息、仪器校准和表征，以及输入信号的描述。

The scope of this effort is to develop a standard for data and metadata content arising from spaceborne global navigation satellite system-reflectometry (GNSS-R) missions, which uses GNSS signals as signals of opportunity, as described in "The IEEE SA Working Group on Spaceborne GNSS-R: Scene Study." In particular, this standard would provide a means for describing: a) The terminology assigned to GNSS-R data and products, such as the product levels. b) The structure and content of the data. This includes, but is not limited to, units of measure, data organization, data description, data encoding, and data storage format. c) The metadata. This includes and is not limited to metadata, methods and algorithms applied to the data, parameters related to the algorithms, citation information, instrument calibration and characterization, and description of the input signals.
