G3000 interfered GPS signal

Hi,

I had some nasty adventures recently on CJ3+. We've lost GPS1 & 2 signal and because of that we've lost AP, YD and both attitude indicators while at FL400 over Mother Russia.
I sent AReS data to Cessna and they said this is normal, AHRS will behave this way without GPS signal. Really??

About week ago had problems around LCLK, during one approach to LCLK both GPS lost signal so G3000 went into DR mode. All happened over LCA VOR. Once turning final signal was regained and it turned out that map shifted around 3NM. So DR mode did 3NM mistake during 2-3 minutes. Shouldn't it inhibit DR while on approach or in Terminal?

Have you got similar issues on Gx000 equiped aircraft?

Best regards
