A mobile phone's AGPS is too off mark in giving locations.
agps does not mean gps using cell phone towers. It uses cellphone towers to speed up fixing the location. You can switch off this feature.
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.
GPS in mobiles have 12channel recievers with only 6 in use. Besides the RF noise in a mobile is very very high and results i n very poor GPS sensitivity and accuracy.
