As to improving ICBM accuracy with GPS (or other satnav), I'm not sure the near environment missile-atmosphere effects wouldn't significantly interfere with signal reception. This would depend on the placement of the aperture and the properties of it's covering material. Putting the antenna on the tailend would be sensible for terminal navigation but then again that's the hot side on the boost phase. I presume such consequences of missile speed to signal reception have been investigated but I imagine the engineering challenges are greater than for subsonic missile systems.

Good post/thanks.

Greater! Yes. I have these problems every time I try to design a hypersonic reentry vehicle.



Congress is doing more than huffing and puffing, it appears:

"A proposed Senate amendment (No. 2185) to S. 1197 would limit the construction of satellite positioning ground monitoring stations controlled by any foreign government on U.S. soil. Such construction would require certification by the Defense Secretary and Director of National Intelligence that the stations could not be used to gather intelligence or improve foreign weapons systems. The proposed amendment would also impose a new reporting requirement on DOD, DNI, and USSTRATCOM."
