I see there are a ton of comments here that I simply don't have time to read, so I'll give you the quick answer.
For this to work, your iPad has to have GPS or Location capabilities. Otherwise, how does the app or the AC know your new location? If you're connected to the Internet via WiFi, your iPad will net a VERY rough location (accurate to within 30'????). If you use an iPhone, it has built in GPS, which will be more accurate than WiFi location.
If I'm doing work were my location is very dynamic (like following the drone in a car), I use a GPS device called a SkyPro™ GPS Receiver. I use the "Dual" model.

This beast is easy to use, extremely powerful and is balls-on accurate. It links to my iPad via BlueTooth and is amazing in every way.
Keep in mind that the GPS pinpoint is at the SkyPro device, not the iPad. So if I'm standing 10 feet away from the SkyPro, the drone will RTC to the SkyPro, not the iPad. Fortunately, this is a battery device. So, in theory, I could carry it with me.
For grins, this morning I placed the SkyPro in my GF's back yard, turned it on, and checked to see if it linked to my iPad in the house 30' with a wall between the two. It instantly linked;

Within 30 seconds, the beast had full satellite telemetry:

So then I decided to bring it inside and place it on the kitchen table:

I've had this beast on the dash of my car IN the garage, and it still sent full telemetry data to my iPad in the house. As an added bonus, I'm able to use a mapping app and remain completely offline. I don't depend on cell service or, god forbid, WiFi service (via a hotspot or whatever).

It's pretty useful. So, anyway... Get one of these; connect it to your iPad via BlueTooth, and your RTC should work. If memory serves, I paid about 160 bucks for mine on eBay. Best investment of the year.
As an off-topic side note, the mapping software I use is Sygic, which downloads your given state(s) and STORES them on the iPad so you can remain completely off-line. This even works with my iPad Air 1 16GB WiFi version (my weakest iPad). Sygic allows 3 updates/year. So far the map of my state has been VERY accurate. I've been using it to get to remote job locations hundreds of miles away from my home.
