It’s the fastest vehicle ever built. It travels the world every day. It could destroy a city if it stopped for a visit. After it’s done traveling around the world it may explore the ocean.
If all the satellites stopped working at once there would be a shower of metal hurtling towards the earth that could destroy entire countries. Or if they disappeared entirely GPS systems wouldn’t work meaning no one would be able to find their way home so we’d become a society of nomads travelling without a clue of where we were.
