You don't agree that somebody could write a software to fake GPS positions? Seriously?

It's a technical fact that this can be done, and it's fairly easy. I do it all the time while I develop XCSoar, to test the software I write.

Your personal opinion on this is provably wrong. Stuff like that cannot be decided by consensus or personal opinion - if it's technically doable, no opinion can ever make it impossible.

(With some more effort, all loggers, even sealed ones, can be spoofed, without ever touching the logger - this has been demonstrated last week by the University of Texas. Never say never.)

Yo Max,

Chill dude. Paul was simply restating the long-held position espoused by the IGC's GFAC.

A committed enough cheater could defeat any of the current security features of IGC FRs; though many of them would require some significant level of complicity by an OO.

What everyone who pushed for GPS Position Recorders was looking for was/is a level of security that makes it impossible for a "casual" modification of a log file by a pilot who needs to eliminate one or two pesky fixes that "accidentally" put him/her into prohibited airspace or to slide a couple of fixes a half kilometer in one direction or the other to take care of a missed OZ. As long as the hardware/software combination is reasonably protected from this sort of casual hacking, NACs may (or may not) choose to promote devices as GPS Position Recorders.

Hi Max,

I guess I just disagree with the IGC on how secure loggers need to be. They
make the decisions. I respect them and everything they do. But I
respectfully disagree on whether products like the Oudie should be approved
for badges and records.

Best Regards,

Paul Remde

This Dutch site says that there is an IGC approved version of the Oudie - with a 12 hour battery and a Nano incorporated internally:

http://www.gliderpilotshop.nl/winkel...roducts_id=778

Unlike the Oudie 3, it does not seem to have a vario.

This product is not shown on the Naviter website. Has the Dutch site jumped the gun on announcing a product which is about to come out?

It is pretty expensive (990 euros) - but if you need a navigation computer and an IGC logger that could be acceptable. It would be the top end of the portable range.

Unfortunately, It is extremely unlikely that the IGC will approve the Oudie

Hi,

I also have Oudie 3 units in stock. I'll have them on my web site later
today.
