They are with us all day. When we wake up, go to school, to work or for a trip, and when we spend time with our families in the evening, too. And at night? In the darkness of the night, they guard us while we sleep. Without them, we would not have navigation in our cars or mobile phones, accurate weather forecasts, and in fact many everyday items, either. Do you ask who they are? None other than artificial satellites! Satellite technologies help us every day. They are the symbol of international cooperation across the continents. And they might enable us to live on this planet for another millennium.
