Does your iPad have a black plastic bar across the top, on the back? If yes, you have a cellular model with GPS antenna. If not, you don't.

Just an FYI the iPad 11 Pro I own does not have said bar. There is the sim card port on the lower right.
Also for new folks always start with with 1st and 2nd post in this thread. A lot of the initial questions are addressed there. I edit it as required.
I don't think I have this tidbit but will add it.
If you have a wifi only iPad and are sitting with a wifi connection your iPad will likely target your location via wifi triangulation. You can see this is Apple maps, Google Maps, Gaia, etc. Hop in your vehicle and then see what happens. Tethering to your phones hotspot will not work. Pretty much any Bluetooth GPS receiver will work including the Garmin InReach. Dual GPS, Garmin Glo, and Bad Elf are popular options.
How can you tell? The easiest way is look for the sim card port on your iPad.
The next easiest may is go to Settings: About: look for Model Name (3 down from the top) Google your model name and you will find your answer. For example: mu162ll/a specs that is my iPad Pro Wifi/LTE model.
