GPS Sensitive to Vibration?

My UBlox LEA6 is glued on top of a carbon fiber mast, pretty much like every GPS I’ve seen.
Every other piece of electronic gear is isolated from the frame by foam or moon jell.

Should I consider adding an insulating layer between the top of the mast and the GPS? Or is GPS function just not bothered by vibration?

I’m not having a problem; I’m just curious.

I have had the little battery inside the GPS detach, which resulted in a total systems failure and crash, with a GPS hard mounted to the frame of a gas powered helicopter with extremely extremely high vibration levels. But I believe that’s the only failure, ever.
