It says here[1] "All GPS receivers capable of functioning above 18 kilometres (11 mi) altitude and 515 metres per second (1,001 kn)[56] are classified as munitions (weapons) for which U.S. State Department export licenses are required. These limits attempt to prevent use of a receiver in a ballistic missile." News to me!

People have built their own, though. It's not easy, but it can be done.

The question is, does launching a rocket into space technically count as export?

depends where it lands, maybe.

Does that law apply GLONASS as well?
