- sbierwagen 11y agoUS-government mandated GPS receivers "capable of providing navigation information at speeds in excess of 600 m/s" are actually covered under the Missile Technology Control Regime. (category II 11.A.3.b.1) http://www.mtcr.info/english/MTCR-April2011-Technical-Annex.pdf http://www.mtcr.info/english/MTCR-April2011-Technical-Annex.... The MTCR has 34 members, basically the G20 minus China and India. Since the MTCR doesn't have any provisions for enforcement, (It's "an informal and voluntary partnership") its US equivalent is the International Traffic In Arms Regulations Act. (Category XV, Section c, if you want to read how the US statute words it. In imperial units, of course, just to make things simple.)
