My mistake. I was referring to mobile phone gps. It is not very accurate. In google maps on my phone, my location is off by about 200 to 300 meters. Not good for giving directions as I am not present on that spot. A left or right turn based on this perceived location can be disastrous.
either you need a new phone or google maps are inaccurate. In Mumbai, on openstreetmap, my phone is accurate to about 10-20 meters which is less than the width of the roads.
I have an application called Google Maps in my mobile ( Samsung Star ). I doub't if there is a GPS in my mobile. The application opens up with my current location as the default map. It has a tiny spot which indicates my location. I believe it uses some triangulation from the cell phone towers. I re-checked my location and it is off-set by about 60 to 70 meters.
