Is it possible to arm Indoors for testing only?

Hi all

For testing purposes is there a way to get a pixhawk to arm and run the motors indoors, for testing.

I have tried turning then all off in the Arming Checks section on Standard Params but it still says need 3D fix to arm and i obviously cant get a 3D fix indoors

Is there some way of getting it to arm and run the motors indoors.

Thanks

Paul

I think this question would be better asked on the arducopter forum
