How accurate is RedLaser on the iPhone?

How accurate is the iPhone's GPS?

  • to within a few feet? Meters? If I were to be standing in a spot and wanted to know the distance between another, how accurate would it be? Thanks!

  • Answer:

    Like all privately owned GPS systems it has an accuracy of ten feet. To get better accuracy You have to have a very expensive commercial or government grade GPS. The ones you see surveyors using have an accuracy of 1cm. That 10' means a plus or minus of 5'. So imagine a circle around you of about 5', the GPS in your iphone could be located anywhere in that circle and have that reading.

Since GPS first came out to the public it has been said to be "within 10 meters" Generally it is better than that. Depending on your GPS you may have a walk/bike/drive mode. If set to walk mode you may get down to the nearest 5' You can do tests yourself. Mark your loction, walk/drive 1 mile. And see what the GPS is telling you :)

For short distances, it is within a few feet. But for cross country travel, about a couple miles off.
