The Sun newspaper in the UK actually published the formula behind Coca-Cola back in the summer of 1993, sadly I neither kept the article nor a record of the recipe. If you can find someone who saves such items, it would be an issue between June and September 1993. Just in case you were interested.
The reason for this is that the American military use something called spoofing. There are two type of GPS transmission as far as I can remember from University : S-CODE and P-CODE. When the US or Nato is involved in a conflict, the spoofing is turned off, allowing accuracies down to about 30cms (I think 1cm is a fallacy). You can always get around the spoofing using something called fast-static GPS. The reason the military code cannot be easily cracked or jammed is because it is only repeated approx once a month, whereas the civilian frequencies are repeated frequently. This is all from memory of my studies over 3 years ago, so don't flame me if im wrong! B
