Also, GPS by design does not provide accurate enough location data to guide a system through preprogrammed routes. With no technical basis to make the the claim, I say the repurposed Soviet cruise missile had control through an airborne AWACS platform.
GPS is good enough to me tell me which side of the road I'm on, or which end of my lounge I'm standing at. Nominally it's accurate to about two meters, way more than good enough to fly a well plotted nap of the earth route.
As for access to accurate topographical data, I seriously doubt if that's a problem in this day and age.
If you are stationary for long enough, your GPS plotted position will bounce around a bit, the rms error is about 200 metres IIRC, but if you're moving that all cancels out in the filtering - the math is way over my head!
GPS for non military use was degraded until Bill Clinton's administration, when "selective availability" got turned off. Prior to that, it wouldn't have been fit for this purpose.
