As for the GPS sats, they constantly broadcast their locations and time. In fact that's the purpose of GPS sats and that's all they do.

GPS sats are vital for U.S. missile' guidance systems, so even a system that can only hit GPS sats is a threat to the effectiveness of these weapons. That is why U.S. considers this Chinese test a potential threat to its military, hence, the protest.
