Well maybe not an error, just that GPS based sat navs appears to have decided my house has moved.
Over the years several cars with their various sat navs have allowed me to define where my home is and then have been able to navigate to within a couple of metres of my drive. I should point out I can find my own house, but the sat nav is useful in allowing me to know my ETA.
Since the start of 2014 my sat nav thinks my home is about 150 metres from where I live. And it's not just me; delivery drivers, who previously would come straight to my front door, are getting misdirected too.
I understand the general way GPS works, but am surprised that such a large error has appeared; I thought the error for civilian systems was only as few metres. Or is there something afoot in the US department of defense?
