Re: iPad GPS accuracy?

The cellular+wifi models have a full GPS. It is called assisted GPS only because it can use the phone towers to acquire an initial position more quickly. This is better, not worse than a conventional GPS system. It works fine outside cellphone range.

Having said all that there is a difference between different GPS units. The quality of the GPS chip and the antenna design do make a difference. I have a dozen GPS units on board and there are noticable variations in the data quality.

I would rate the iPad GPS as reasonably good, but there are better units.

One interesting feature is that it is also a GLONASS receiver
