New to the hobby and still gathering knowledge prior to taking my P3A out. I have a ipad mini with GPS but only if connected to a wifi network.
If i cache the map of the area im going to be flying in at home on my wifi network and then drive to that area and use the ipad mini without GPS will my home point be recorded ? Do you need GPS to properly fly the P3A ?

From what I have experienced, you need the GPS to be able to use the functions in "F" mode. If you cache your area and don't turn off your I-pad, I think you will be able to view the area ok in the maps.

The drone uses gps to aid flight - you don't need it on the ipad to work

Yes, your homepoint will be recorded wonderfully because the AC has it's own GPS module.  You don't need GPS on your iPad or tablet unless you want to reset the homepoint to your current position.  For example, you're on the move, walking along or whatever, so you would want to reset the homepoint to your iPad's current position periodically since you don't want it RTHing and flying home a mile behind you.  
Otherwise if you're simply standing in one spot, there's no real reason to have GPS on your iPad, tablet, etc.

And be Vary careful with rth. It's been said there's a glitch when it returns to home and switches home point 2 miles away from you and you can lose it so always keep and eye on it home point and start off point should have been the same

Hi Guys! I am new to this whole drone thing. I checked out many beautiful videos of landscapes from many drones and the Phantom had the best and most stable shots in my opinion (for a drone in its price range). Very nice work DJI and thank you for the nice camera hardware! Last week I got the Phantom 3 4K. As I said, nice camera, 4k, very stable image and flight time is great and it has a tracking function. Threads are my most important things for a drone. But, I misted out on the deep study of the tracking ability. I saw a youtube clip that showed me active travcking on a P3 4K and it looked great. But Now that I have this drone, it immediately get GPS single loss. When I start it al up it says that I have "Satellite Position Off. Fly with caution" and a very persistent computer voice that says "Atti mode" all the time right after I turn it on. Ofcourse it is set on F mode, because I want to play with the Active tracking an Follow me abilities, but I cant because the GPS is weak no matter at what open space I fly until now. I expected to this drone to fly almost everywhere so it can make nice videos too. But if the GPS issue is so weak (yes it is switched on on my IPhone 7 plus, firmware is up to date, recalibrated all, restart hardware, changed locations wide open spaces). I never got a good gps signal. So I started Googleling this GPS issue and it turns out that it a really common issue.
What is the real issue about this low GPS? Is it the remote controller, my phone, the drone maybe, software issue? I simply think that it SHOULD work most of all places, so you can used all abilities that I payed for.
Is this an issue that DJI really acknowledged and they are working on a structural solution? Or is this something that they leave to us to solve? Why is it such a big issue?
Will a fuction like active tracking (obstical tracking) be come to the P3 4K addition? I mean, its not really something new. This topic filled me in: https://forum.dji.com/thread-44206-1-1.html
Why not for the DJI app for the P3 4K?
I find the GPS loss issue for this drone really a bother sinds Its a really important function for this drone. So my main question is, is DJI working on a weak GPS solution and of so, is it a priority for them to solve this issue?

Sorry for the long story, but since I am new here, I am unable to start a topic and I cant find a way to win some points yet.

Why? RTH will work even if you switch the controller and iPad off and put them down a hole. It is the built-in GPS in the aircraft that does the work, it has nothing to do with your iPad. When you start the motors, the GPS receiver in the aircraft records its position, and it is that position it will return to.

Whether your iPad has GPS or not makes no difference.
Your Phantom has a very good GPS receiver of it's own and it uses that to record its home point and all flight functions.
Go out and practice RTH and learn what it does and how it does it.

You should be able to start a new thread by going back to the Phantom forum start page and clibking on the blue New Thread icon in the top right.
It's quite normal to get a Satellite Position Off message when you first power on and for this to go away as your Phantom locks on to more satellites.
GPS Weak messages sound like they relate to the GPS signal your phone is getting.
Forget about Follow-Me for now and see if your Phantom works properly in P-GPS mode.
To get good satellite reception, the Phantom (or your phone) needs a good unobstructed view of the sky.
If you are under a roof or close to trees, buildings etc with a lot of sky blocked this will reduce the number of satellites your Phantom can see.

Does the Phone have to be connected to the Controller? Does the controller have gps for follow me?

there is absolutely no connection to RTH and atablet having gps or not.


You do know one does not need ever use RTH ,
it seems new users inmediatley want to do so.
To me take off, I fly  I land.
But I still have my p3p over a year later ........

Phantoms have a full GPS system builtin. It doesnt use the tablet for basic home point

good luck and have fun flying

The phone or tablet is normally connected to the RC via USB cable if it's a P3 Pro or P3 Advanced, the P3 Standard uses a wifi link to phone/tablet. The phone or tablet needs GPS if you want to use 'follow me'. If 'Follow Me' or 'Set RTH to controller position' is not required then all other intelligent flight modes should work without requiring GPS. As said above the initial home position is set by the aircraft GPS when the motors are armed.

Edit:- From a practicle point of view the phone or tablet would always be connected to the RC for control information and video. But the RC controls the aircraft motion, and can work without the phone/tablet if needed (if they crash for example).

Thanks and i understand you dont have to use RTH all the time. I was actually going to post another question  asking why so many users are using RTH so frequently especially with the fly away issues in the app

Same, I dont get why we would use return to home or push the limits on the range.

How much is the full amount of satellites we can have?

"Same, I dont get why we would use return to home"

RTH is one of the most important operations to learn and understand.
It is very reliable and useful but if you ignore it until the day you need it, you probably won't come home with your Phantom.

"How much is the full amount of satellites we can have?"

If you have a Standard the number may be close to 12.
If you fly one of the newer Phantoms, you can pick up around 20 sats at times.

use it, learn it, so when you need it , it will work correctly

but some seem to use it without knowing about its limits , settings or even how to fly the quad in general
that usually is a great way to not keep it long.

good luck and have fun flying!
