ISO 22009:2009描述了主要的磁层大尺度电流系统和地球磁层中的磁场，并提供了磁层磁场模型的主要要求。ISO 22009:2009中没有考虑电离层电流。ISO 22009:2009包括一个模型的工作示例，并建立了根据空间环境条件变化的磁层大尺度电流系统的参数。ISO 22009:2009可用于开发磁层磁场的新模型。这种模型有助于研究地球磁层中的物理过程，以及与开发、测试和估计在空间环境中运行的航天器和其他设备的开发结果有关的计算。标准化地球磁层磁场概念的主要目标是提供地球磁层磁场的明确表示；空间实验解释和分析结果的兼容性；地心距离为1.0至6.6地球半径RE的空间磁层电流磁场的劳动强度较低；以及空间环境中地磁场所有元素的最可靠计算。在开发航天器磁定向系统和预测磁扰动对跨洲管道和输电线路的影响时，ISO 22009:2009中提出的磁场模型可用于预测空间辐射条件，包括强烈磁扰动（磁暴）的时期。
ISO 22009:2009 describes the main magnetospheric large-scale current systems and the magnetic field in the earth's magnetosphere and provides the main requirements for a model of the magnetospheric magnetic field. Ionospheric currents are not considered in ISO 22009:2009. ISO 22009:2009 includes a worked example of the model and establishes the parameters of magnetospheric large-scale current systems that change according to conditions in the space environment. ISO 22009:2009 can be used to develop new models of the magnetospheric magnetic field. Such models are useful in investigating the physical processes in the earth's magnetosphere as well as in calculations associated with developing, testing and estimating the results of exploitation of spacecrafts and other equipment operating in the space environment.The main goals of standardizing the concepts of the earth's magnetospheric magnetic field are to provide an unambiguous presentation of the magnetic field in the earth's magnetosphere; compatibility for the results of the interpretation and analysis of space experiments; less labour-intensive calculations of the magnetic field of magnetospheric currents in space at geocentric distances of 1,0 to 6,6 earth radii, RE; and the most reliable calculations of all elements of the geomagnetic field in the space environment.The magnetic field model presented in ISO 22009:2009 can be used to predict the radiation conditions in space, including the periods of intense magnetic disturbances (magnetic storms), when developing systems of spacecraft magnetic orientation and when forecasting the influence of magnetic disturbances on transcontinental piping and power transmission lines.
