As Mike says, the artificial generation of GPS signals has always been possible, as have several other possible methods of cheating. Its a bit of a yawn, really.
Anyone who wants to come to one of my competitions and try it on is welcome. I predict they will be shown the gate in about 2 days, and will never fly a glider in a competition again. It will be definitely more fun to just fly the task. And no (before you ask), I am not going to tell you how I will know.

Subject: Re: [Aus-soaring] Forgery and sabotage Mark, That sort of stuff has been available for a long time, just cheaper and even more ubiquitous now. About 12 years ago a guy claimed on r.a.s. that he had done this. He knew some guys in military electronics in the US. He thought the IGC security requirements were ludicrous because of this gaping hole in the security. You probably don't need to buy one, just know somebody who works at a small company that has one and that he can take home on the weekend. This was all discussed extensively when the IGC decided to adopt GNSS loggers and they even made a rule "It is prohibited to feed data into the device via the antenna". Makes all the rest of the security song and dance look pretty silly. As ever, security comes down to people - in this case the O.O.s. If the O.O. is present at the beginning and end of flight and scutineers the glider you'll get reasonable security. The IGC decided they couldn't trust the O.O. so tried to build the security into the hardware. Epic fail. If you own an IGC flight recorder just think of all the money you were forced to spend for non existent security. Come to think of it, a device like this would be great for AATs. Fly the task and record the GPS position and move it a little further each fix until you've flown a greater distance. Feed that through the device and into the FR in near real time.
