Hi, "Oh my god ..." does not work for me since I don't belive in that kind of "god". It's not a balony, just some information. Did you read the article till the end? After a few paragraphs I said "oh, it is just a jamming", but furthermore the team explained that some already available devices are capable to obliterate the true signal with their own and DO really spoof and make the GPS receiver think it receives the "good" data.
I didn't want to say that OpenBSD's usage of GPS is wrong, just wanted to drop in an interesting and possibly related article ... Sorry for the noise.
