GB/T 46195-2025

This standard specifies the application of the International Reference Ionosphere (IRI) model and its extensions to the plasmasphere for characterizing Earth's ionospheric and plasmaspheric electron density, temperature, and composition. It is primarily used in aerospace engineering for satellite communication system design, space weather forecasting, and spacecraft orbit planning to mitigate signal propagation delays and radiation effects. The standard applies to mission planning and testing contexts involving low-Earth orbit and geostationary satellites, as well as ground-based radio propagation analysis.
