GPS affected by snow?
I'm sure I heard on the news recently with all the snow that drivers were finding their sat navs stopped working when it got very heavy.
I was very surprised to here this - I had always assumed that the frequency that GPS operates on, aprox 1200MHz and 1575MHz if I recall, should not be affected by/reflect off precipitation of any sort. Is this the case though? Could really large snow flakes in the air disturb the signal?
I wondered if perhaps it was physical snow accumulations on the car itself that were causing the signal to be lost.
