Narrative:

Climbing out in IFR conditions I lost GPS signal to my kns 750 which skewed my G5 heading. I was given a heading and had to check my magnetic compass to comply. My GPS signal came back after about 5 min. I don't believe their was any separation issues. I landed and called my mechanic and told him what happened. He thinks with the raim (receiver autonomous integrity monitoring) that we have to ground the control surfaces. He has only heard of this one time before. I told him that I will not take that plane up again in IFR conditions without fully going through the panel.
