Should this prove to be GPS spoofing it has big implications for NAS integration, everywhere.

Sad to hear.  Maybe they should have set RTL+X, on GPS failure and set X to an offset of several meters from where the operators are.

I doubt they start using the S-100 during a GPS Jamming operation maybe it's a dead-reckoning algorithm problem and we maybe never know since the GCS was destroyed.

@Ellison, what use would that be if the GPS is jammed?

Comment by Ellison Chan on May 11, 2012 at 9:39am

I'm thinking they use a little more sophisticated RTL algorithm than ours.  I can think of one where you're always calculating the RTL offsets from current location and on loss of GPS, you can attempt a backtrack to launch without the GPS signal.

Maybe they should look into a shelter upgrade??

Condolences to the families, and a speedy and full recovery to those injured.

Knew him well. Good guy, great engineer. Taught me a lot. 

Jozef, I will miss you.

Sorry to hear that Tobias, its a great platform with a bright future. Lets see what the accident report brings.

Condolences again to all those that knew Jozef.

@Ellison, OK, assuming they have an inertial dead reckoning system, as a backup, that could help.  And it's a fair assumption that they did.

The problem is, I think, if somebody was spoofing the GPS signal, that would probably over-ride the inertial system.  Similar to what happened with that drone in Iran.

Regardless, it doesn't sound like the idea of GPS spoofing is anything other than supposition at this point.  But, if it was spoofing, and it appears they even managed to steer the craft into the command and control station, that's a pretty frightening prospect that they had that much control.

Yes the GPS does not necessarily know its being spoofed.

But I doubt it was that, it was just what was said to the press.
