Amazing the kind of stuff that's available off-the-shelf these days. I reckon if you put one of these and a IGC-approved logger into a barometric chamber, you can create the world record datalogger trace of your choice: http://labsat.co.uk/
The labsat unit takes a GPS or GNSS datafile and plays it back as RF, so a nearby GPS device will actually believe that it has followed the course described by the trace. With a barometric chamber you get the pressure altitude axis as well. The result will be a datafile you can extract from your IGC-approved logger which says pretty much whatever you want it to say. It costs about UKP7000, so you might want to buy into one in a syndicate with other like-minded cheats. "Tell you what, I'll claim the distance record, why don't you claim the speed-around- a-300km-triangle record?" Meanwhile, there're also ways of preventing other people from getting logger traces. For about twenty bucks you can get one of these: http://www.dealextreme.com/details.dx/sku.35827 Couple it with a 12V power source and hide it in the tiedown kit bag in whichever aircraft is at the top of a competition leaderboard to produce a "I would have won that comp if it weren't for that goddamn GPS malfunction!" result. Maybe you're not even competing in the comp, you just want to stir trouble 'cos you're taking the piss. It comes with free delivery :-) The equipment required to both forge and sabotage GPS traces is readily available off-the-shelf at prices that individuals can afford. For how long will GPS continue to be trusted for world record and competition claims? Will we get back to using barographs and cameras? Are the requirements on official observers good enough to protect against forgery? I love the 21st century :-) - mark -------------------------------------------------------------------- I tried an internal modem, [email protected] but it hurt when I walked.
