摘要: Space weather is a term that refers to the dynamic, highly variable conditions in geospace environment. This includes on sun, interplanetary medium, and magnetosphere-ionosphere-thermosphere system. Rapid changes near-Earth space environment during major geomagnetic disturbances can affect performance reliability of both spacecraft ground-based systems. Modern systems subsystems appear show an increasing susceptibility effects including communication, navigation, reconnaissance satellite operational anomalies. trend probably due “softer” designs electronic components, reduction subsystem sizes, increases demands. The elements contribute anomalies be reasonably well identified. paper reviews anomaly trends assesses identification potential prediction causative weather. We discuss principal adverse environmental presently known cosmic rays, trapped magnetospheric radiation, solar energetic particles. scientific underpinnings for present methods are also considered.
