How do I determine if my Ipad has GPS?

You already have the answer - but if you insist upon seeing the presence of GPS hardware on your device, you can install an appropriate App to confirm presence of specific hardware features.

Take a look at System Status Pro: hw monitor - available from the Apple App Store - which can show you something like this:

I hope this fully resolves your query.

If your iPad is a WiFi & Cellular model - then it will have aGPS capabilities. If by contrast your iPad is a WiFi Only model, then your iPad does not have built-in GPS.

For iPad, aGPS (Assisted GPS) features are an integral part of the Cellular chipset. Position information is derived from a network lookup of CellID, known WiFi networks and GPS positioning.

I hope this helps to clarify.

It can be difficult to search effectively for things you don't know much about. This is were I find Wikipedia to be useful. It's not the be all and end all of references but, it can often give you enough information to start understanding what kinds of terms you should be using when you search.

It's not. Why do you think that?
