GB/T 31158-2014
ActiveIonospheric total electron content (TEC) disturbance classification
电离层电子总含量（TEC）扰动分级
Application Summary AI generated
This standard defines a classification system for disturbances in the ionospheric total electron content (TEC), categorizing events by severity based on deviation from background values. It is applied in space weather monitoring, satellite navigation (e.g., BeiDou/GPS), and high-frequency communication systems to assess signal degradation risks. The classification aids engineers in predicting positioning errors and communication blackouts during geomagnetic storms.
