Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules of Standardization Documents" drafted.

1 Scope

This document gives the spectral range division of solar electromagnetic radiation in free space, the total solar irradiance of Earth orbit, the sun of different planets Standard values for total irradiance and solar spectral irradiance.

This document is applicable to spacecraft design, environmental analysis and test parameter design of ground simulation tests, spacecraft on-orbit failure analysis, etc.

It can be used for optical system design, spectral calibration, etc. in space missions.

4 Solar spectrum range

The space solar spectrum can be divided into the following bands according to the wavelength (lambda) range.

a) Gamma rays. electromagnetic waves with a wavelength range of 0.00001nm<=lambda< 0.001nm.

b) X-rays. electromagnetic waves with a wavelength range of 0.001nm<=lambda< 10nm.
