In a military context, they do propagate the key via their own, robust infrastructure. Over time, they've (USG) released keys and generally opened it up to the public, but they reserve the right to lock it down again.
As a result, while we have sub-5ft accuracy now, there's no guarantee that in war time, we won't lose that.
- codewritinfool 7y agoIs this correct? SA, or Selective Availability (an intentional degradation of accuracy) was turned off in May of 2000. This allowed existing civilian C/A code GPS receivers to generate better solutions immediately. It did not involve any keys or release of keys. I've never seen any "released keys" and have never heard of this. When did this happen?
