This document provides guidelines for specifying the qualitative estimation of the solar wind energy input into the magnetosphere with use of operative ground-based information on the polar cap magnetic activity (PC index). The solar wind energy incoming into the magnetosphere predetermines development of the magnetospheric disturbances: magnetic storms and substorms. Magnetospheric disturbances include a wide range of phenomena and processes directly affecting human activity, such as satellite damage, radiation hazards for astronauts and airline passengers, telecommunication problems, outrages of power and electronic systems, effects in the atmospheric processes, and impact on human health. This document is intended for on-line monitoring the magnetosphere state and nowcasting the intensity and extent of magnetic disturbances as well as parameters of the high-latitude ionosphere. The method and accuracy of estimating is ascertained by close relationship between the PC index and interplanetary electric field (as the most geoeffective solar wind parameter), on the one hand, and between the PC index and magnetoshpheric disturbances, on the other hand.

This document, by using a model that reproduces the fluctuations of radiation belts, defines the calculation method (orbit, operation period) of the radiation fluence received by a satellite. The quasi-dynamic model of Earth's radiation belts adopts input parameters (index values) to predict variation. The input parameters are selected from those that are easy to obtain data and have high correlation with the variation in Earth's radiation belts. NOTE This method is an engineering method used for satellite design and similar purposes.

ISO 12208:2015 describes a method to estimate energetic proton fluences in geosynchronous earth orbit (GEO) over a long duration (beyond the 11-year solar cycle), and presents guidelines for the selection of a confidence level in a model of solar proton fluences to estimate solar cell degradation. Many of the proton data observed in GEO are archived, for example from GMS (Japan), METEOSAT (ESA) and GOES (USA). This method is a direct integration of these fluence data (or the observed data over 11 years is used periodically). As a result, the confidence level can be selected from a model of solar proton fluences. ISO 12208:2015 is an engineering-oriented method used for specific purposes such as estimating solar panel degradation.

ISO 15856:2009 is the first part of a series on space environment simulation for on-ground tests of materials used in space. This International Standard covers the testing of non-metallic materials exposed to simulated space radiation. Non-metallic materials include glasses, ceramics and polymer-metal composite materials such as metal matrix composites and laminated materials. ISO 15856:2009 does not cover semiconductor materials used for electronic components. The types of simulated radiation include charged particles (electrons and protons), solar ultraviolet radiation and soft X-radiation of solar flares. Synergistic interactions of the radiation environment are covered only for these natural, and some induced, environmental effects. ISO 15856:2009 outlines the recommended methodology and practices for the simulation of space radiation effects on materials. Simulation methods are used to reproduce the effects of the space radiation environment on materials that are located on surfaces of space vehicles and behind shielding.

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.
