The Impact on Security & Defense 2019 20 Accepted on 2019 Jun 7 Space Weather refers to variations induced by the Sun of the Earth’s space environment and the impact that these variations can have on technological systems and human health. During space weather events, technology such as radio communication and GNSS positioning, can be seriously affected. Space weather can cause the loss of satellites, increase radiation levels at aeronautical flight levels and on the ground, and has the potential to catastrophically damage power grids. We review the space weather cause-effect chains from the source to the affected technologies with special attention to the impact on security and defense.
