DESCRIPTION
PD ISO/TS 21979:2018
This standard PD ISO/TS 21979:2018 Space environment (natural and artificial). Procedure for obtaining worst case and confidence level of fluence using the quasi-dynamic model of earth's radiation belts is classified in these ICS categories:
- 49.140 Space systems and operations
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.
