Can fog disable GPS

Just had a harrowing experience. Everyone on FB bragged about fog, and how Christmas lights look especially beautiful in it. I drove eight miles until I hit fog, and hung a right into a little neighborhood where all the streets loop around willy-nilly. The lights were lovely, but after twenty minutes of loop-the-loop, I realized I was lost. About the time the neighbors started to call my car in as suspicious, I hauled out my GPS. Did you know it can’t find the satellites through the fog? Through good fortune, I eventually found my way back to the main streets. Then the GPS kicked in.
