Satellites no longer just relay TV pictures and phone calls; they are vital for both daily life and modern warfare. Knocking out or blinding a satellite could mean your car’s GPS system goes blank and your bank cards stop working. When you switch on the TV to find out what’s happening you may find just a blank screen. After a few days the supermarkets’ delivery systems, both to their stores and your house, would be in chaos. Without GPS ships and planes would struggle to navigate, and in an extreme scenario the electricity grid could go down. As for getting a weather forecast – forget it.
