Good day Tahoe_Ed

This is exactly my frustration.
I have done as you said - which is also what the manual says (like "cache in background) - which is also what I read on the forums.

In my case with iPAD Mini 2 WiFi, when I get to site I see only square blocks like "graph paper" and my flight records says "map loading" even after I get back to an area with proper WiFi. Even areas that displayed the correct location that I flew within WiFi range loses the location name and reverts back to "map loading".

Perhaps it is time for me to ditch the Inspire and move up to the S900 with GH4 sooner rather than later.  I need a airborne platform for the thermal imaging payload anyway.

;-)

Why do we need 2 GPS systems to make the P3 works is the question I am asking to myself and to the  ...

You don’t need 2 GPS devices.
In fact the Phantom does not need any GPS.

* In ATTI mode the Phantom flies without any problem without GPS.

* However, if you want your Phantom to return home in a case of emergency (e.g. lost signal) the Copter needs to have GPS. How should the Copter know where home is without GPS?

* And in “Follow me” mode you need a second GPS device so that the Copter knows where the person is, whom it should follow. How should the Copter follow you without knowing where you are?

The copter and the remote control are linked together with radio frequency No .?
Look at this video. You will see the GPS inside the Phantom 3 bird.

The GPS signal from the bird is transmitted to the Radio Contol using radio frequency and the radio is linked to the tablet with the cable no ?
Maybe I am stupid. I just want to understand the concept properly from DJI.

Can DJI answer this question please ?

ghoonk already answered that question: No, there is no GPS in the RC of the Phantom.

I know there's GPS inside the Phantom.
Of course there is!
Nobody ever said anything different.
Everybody knows there's GPS in the Phantom!

But for ATTI mode you can turn it off and for RTH you need it.

However, the Phantom cannot find the RC using just the radio signal. One radio signal is not enough to find a location in 3 dimensions. That's just a technical fact.

Therefore you need a second GPS device. But you only need it for “Follow me”. If you don’t have a phone/tablet with GPS you cannot use “Follow me”. But you can use everything else.
So what are you complaining about?

I am not complaining at all. I just wish to understand all the concept. Sorry , english is not my first language.
Where I fly most of the time there is no cellular network available.

So I have to get the map where I plan to fly download in my iPad. My iPad is Wi Fi only.

The return home works perfect that way for me.

And if I have a cellular network available where I want to fly I just set my iPhone share connection with my iPad at it works perfect for follow me and so.

Thank you both of you.

For the all Intelligent Flight Modes the tablet or the iPad must have its own function GPS or not?

I hope someone here can answer my question. When in follow me mode does the P3 maintain a set altitude while the RC travels either uphill or downhill or will it adjust it's altitude to maintain the same height above the RC as it travels up or down a mountain road. Thanks in advance for your forthcoming answers

Here is what i just did today.. Found out the Litchi still works same way on P3 then it does on 2 series. I preplanned this flight at home, drove to the site and launched. Everything worked the same as the P2 series. Im going to test follow me this weekend using this app.

Might I add that you would also need the second GPS for dynamic home point usage. Meaning you could take off from one point and change your home point if the need should arise. Just saying for those who don't already know this functionality.  

Just a though for those who complain about altitude restrictions. Why would want to fly more that the 500m limit altitude? Yes you could take of from a hill and fly well above the limits, but then you need to use your common sense. Just because you can doesn't men you should. DJI has done a great job with the lastest firmwares. It helped me save my P3P from a certain crash. Any other copter would have fallen smack to the ground. Just watch my "church tower crash" video and you'll see. Some say it was pure luck, I say it was DJI ingenuity.

[I assume you want this question asked in this (currently) sticky thread. Let me know if I should start a new thread]

Have the firmware updated and having using the IOC features for a few days, but I can't get Follow Me to work, even though the other modes do. I have the left at F, the bird is flying, it's above 10 meters (and certainly below 200), but it isn't following.

Note that I'm just walking right now, but I've gone a couple hundred feet.

Can anyone guess what I'm doing wrong?

DJI-Dave: please take note. These speed limitations are not necessary on a $1300 "professional" item. I have been a huge fan of the P3 until recently. It seems the recent firmware upgrades have added limitations. The warmup period on the craft also is a pain, when before I could start up and go. Hopefully DJI can listen to their customers. As soon as there is a product on the market with these features without the limitations, I'll be switching away from DJI.

That tracks. When it wouldn't connect, it complained about weak GPS signal. When it would connect, it would disconnect a few seconds later.

Other times, it would tell me that it had a mission conflict.

At any rate, I'll try location services on my device (iPad Air 2) tomorrow.

DJI-Dave Posted at 2015-9-8 06:35

Hi Dave, I know you're busy actively supporting us on these forums - (BIG THANK YOU), but I just have to ask how close is the updated manual with the new features? And can we have 2K on the P3pro camera too at 50/60 frames?
Thanks again,

GPS information from the phone isn't handed over to the tethered device, which in your case, is the iPad Mini WiFi. I learned that the hard way as I also have an iPad Mini 3 WiFi.

Here's what I know

- The iPad Mini Wifi does not have GPS hardware. When I am on the go, iPad mini 3 tethered to my iPhone, Google Maps isn't able to lock in on my location the way it does on my iPhone.

- There is a GPS receiver in the DJI Inspire 1. This is mentioned on Page 15 of the DJI Inspire 1 user manual v1.4. The Inspire 1 supports Dynamic Home Point. I do not know if the Inspire 1 will require the tablet/phone to have GPS hardware to use Follow Me, but I will test and report it if no one from DJI confirms this.

- Page 12, 13 and 14 of the DJI Phantom 3 Pro/Adv user guide v1.4 do not mention a Dynamic Home Point nor any mention of GPS hardware on the RC. As such, I am inclined to believe that there is no GPS receiver on the Phantom 3 Pro/Adv RC. This leads me to believe that the Follow Me function requires the tablet/phone to have a GPS receiver

What kind of warmup periods are you getting from your P3P? Mine is ready to fly in P-GPS in under a minute from powering up the battery. I fly in Dubai and Singapore.

I believe this is specific to Follow Me, based on the following logic:

1. Follow Me requires the Home Point to be dynamically updated, i.e. every second (?)
2. POI does not - you fly to where you want the POI is (regardless of Home Point), mark the POI as the center of the flight circle, set radius, etc - this uses the GPS on the aircraft and isn't dynamic
3. Home Lock uses the Home Point. The P3P does not have Dynamic Home Point, so it will always use the launch coordinates as the Home Point. This might be different for the Inspire 1 as the Inspire 1 supports Dynamic Home Points
4. Course Lock doesn't use GPS. It uses compass to establish bearing.
5. Zip Line probably uses the GPS on the aircraft - fly to and mark point 1, then fly to point 2 and mark, then execute

I could be wrong, but this is my understanding of how the IOC functions work, and why they work that way.

This is my test of the Go Home yesterday using the Go App. Screen was recorded off my tablet. Im using a Galaxy Tab Pro 8.4. Wi fi only. GPS works good with it. At start up you have to go to the recomended altitude to start. Once started, you can lower the Altitude and distance at any time just my moving the sticks and it will remember that setting. I started out at 55ft and at end, it was folowing me at 17ft off ground and less then 10 ft away. if you walk towards the phantom, it will move away automatically to keep the set distance like i described in the video.

Got the same problem here with my IpadAir2 wifi only, when I initiated Follow me, it turned 90 degree Clockwise  (looking from the bottom) and it won't follow. But using my Iphone works great. Then tried to use Ipadair2 again and this time the Ipad connected to my Iphone, it still didn't work, same thing, it rotated 90 degree clockwise and did not follow, just hover up there.

I understand your frustration and I am sorry to hear this.
You should not be having a very long wait for warm-up. They lock-in or warm up extremely fast. You should've seen how long it took for a P1 or a 450 or 550 with a Naza system to lock-in.

Now I know that the problem is that my device has no GPS at all.

So the confusion came from the error message in the Go app, which should specifically call out that it's looking for GPS signal from the device. Just saying "GPS signal too weak" is a head scratcher for someone thinking satellite to RC and looking at full bars in the app.

My feature request would be to change the message to say "GPS signal from device too weak" or better yet, "GPS signal from device does not exist".

Good idea!

Problem today with Nav mode.  I flew about a dozen waypoint missions, all the same route.  I was experimenting with the 3 options.  On one of the starts, as soon as I hit the apply button and it finished its calculations, my I1 began a quick descent from about 10 feet and touched down with the gear up.  Luckily I was over soft grass so I don't think any damage was done.  What I don't get is why it did this on only one mission.

Couple other questions came up.

1.  I couldn't come up with a firm grasp on what the difference was between modes.  
2.  Will it start recording as soon as the mission begins?
3.  When will it stop recording?  You cant see the recording options while the nav mode is up.  I didn't want to hide it since I couldn't figure out how to bring it back to cancel.  Keep in my mind my previous experience with the rapid descent.  I wanted to be able to cancel quickly.

Sure would be nice to have some thorough directions!!!
