Loran is ground based far easier to get working than a few dozen sat launches.
N. Korea , and a handful of countries have the nuke and the rocket to set the western world back 100 years.
It's more likely that a lifeform from another galaxy would have the ability to take out 24 independent satellites than any country on Earth (including the US). I don't believe that even the United States has the technology to destroy a single orbiting satellite, except in the movies.
And besides, if in an instant we were set back 100 years, seriously, how important will GPS be? I doubt there'll be much more recreational cruising.
