[amsat-bb] GPS limits

[Bruce Perens]

I believe the Missile Technology Control Regime, a 35 nation informal
agreement, not a treaty, was updated in 2016 to limit civilian GPS system
speed two 600 meters per second, and to exclude from consumer equipment
those GPS designed for missiles and autonomous aircraft carrying more than
500 kg payload.

How or whether each country implements this is entirely up to them.

I have a feeling there might still be a regulation in the EAR. But I
haven't found it yet.
