   I believe it's what they call an urban canyon. When you have something
tall - usually a building - which reflects the GPS signals on one side of
you, you will appear to be in a different position than where you really
are. Whatch your HDOP values - it's the third of the slash separated values
shown by TangoGPS on the main screen. If it's as much as 4.5, the position
shown can easily be 30 - 40 m off.
