Since the earth, as well as the satellites on which the GPS information is 
dependent, are all in constant motion, a destination cannot be exact.  For this 
reason, the accuracy of a destination point is approximately thirty feet, 
regardless of the GPS program being used.  Terry

  Often when I ride in a taxi I overhear the driver’s GPS. Their GPSs, Tom Tom, 
Garmin and the like, seem to have about the same accuracy as the iPhone apps. 
Meaning, they too can be off several addresses. It’s more likely than not that 
the destination is announced before the address is actually reached. I’ve had 
pretty much the same experience with several iPhone apps.

  Quite often, I am told that I'm 2 or 3 doors away from where I actually am. 
It's not just the iphone that's given me these slightly off results either. 
I've accepted it as inherent inaccuracy in GPS. Mind you, I have sometimes been 
indoors when I've got these results, so it may be a bit unfair to judge 
anything like that.

    Hello,

     

    GPS accuracy varies depending on how clear a view of the sky you have. So 
if you're in a vehicle, you can often improve accuracy by putting your device 
near a window. On the street, there's not much you can do. The weather can 
affect accuracy, for instance. So maybe you'll get a better signal another day.

     

    Best,

    Anna

      I am having difficulties getting accurate readings from the GPS.  For 
example when I use DARK SKY it gives the location as three doors from where I 
am.  I also notice this with other APs. 

      Is there a way to reinstall the GPS software without destroying other 
settings?

      Thanks!
