@alexz: Unless I'm mistaken about the current spammer motivations, the target is Google and other search engines, rather than getting direct "clicks" through here.

They want their online "XYZ" shop to be the number one result when someone searches for "XYZ" or any number of related terms. So they spam blogs, forums, wikis, etc. They basically use any site where they can post their own content as free (or almost free) advertising. They are parasites.

I don't think simply adding more satellites from other systems will achieve very much in terms of accuracy. It will give better coverage and some of the errors will average out, but nothing huge.

Instead, I'm looking forward to the L2C signal of the new GPS satellites due to be launched in a few years. Then GPS receivers will be able to measure the signal delay added by passage through the ionosphere. I'm not sure what sort of accuracy that will allow, perhaps sub-metre.

(Look up "GPS modernization" on Wikipedia)
