Working Group 4 of international standardization organization – Experience of developing the standards of space environment Original Research Article

Over the past decade space environment international standards have been developed within the scope of ISO WG4 activities. This has been the first attempt to develop international standards of physical phenomena of natural environment such as galactic cosmic rays, solar energetic particles, the Earth’s magnetic field, the ionosphere, the plasmasphere, etc. The main difficulty faced when developing the international standards is the lack of common methods for characterizing many natural phenomena. However, if methods have been successfully developed, such standards can play an outstanding role in the engineering requirements for spacecraft designs. This report is a survey of the current status of the international standards under development within the scope of the WG4 activity plan.
