    You will have to make this mod. I went from 4 or 5 satellites on the ground to 7 or 8. I never had 12 in flight until the mod. Improve GPS signal on Phantom 2 Vision+: http://youtu.be/q31s6NDFUlA

    I used heavy duty aluminum foil with duck tape covering the other side

    Buy aluminum duct tape for duct work , then cover with packing tape. It's stickiy on one side. The packing tape insulates it. Aluminum foil isn't sticky and regular duct tape is heavy.
    You can find this tape in hardware store or Home Depot

    I have found for my area that this satellite prediction website (http://satpredictor.navcomtech.com) (flash required) is pretty spot on. Usually within + or - 1 of the Sats I am able to lock onto. Fortunately, there are only a couple times a day in my neck of the woods, where the coverage is marginal. From what I have read the mod seems to work for some, however not ready to open up my bird for the mod just yet. When and where I fly, I typically get anywhere from 8-10 Sats.

    With my first bird I got 10-12 all the time. The new one I have only flown once and had 8 sats on the short flight I had it on.

    All of this feedback would be more interesting if each poster would run the sat predictor to see how many were available. My case was poor but I got up to 7 of the available 8 at the time on my third flight. I can't be too disappointed is I got 7 or 8 and only 8-9 are available, 10 or more would be unrealistic... Right ??

    On the ground: 6-9 sats
    In the air: 7-12 sats

    For me it doesn´t make sens all the time. Sometimes I get 9 sats on the ground with large buildings around and other times I get 6-7 sats in a open field. Maybe it depends on weather.

    Had 13 showing once.

    I flew with 10 sats yesterday evening. This is not unusual, sometimes I get more. I am using a stock Vision+ without the tin-foil mod (although, I have now bought some self-adhesive tin-foil and plan to fit it soon).

    I did the mod and a minor addition of wrapping the GPS cable in foil (a suggestion from an aviation electronics wiz friend of mine). Amazing!! My P2V+ can now see the predicted number of satellites and then some with a bit of height (and additional 1-3 satellites.) But the big differences is maintaining the number of satellites and how quickly at start-up they are found. Basically, its immediately after the quad finishes its start-up rituals.

    I used regular aluminum foil and a bit of Scotch tape. I'm impressed. (But not with DJI who should have provided a factory solution asap.)

    A very useful tool: http://www.spectraprecision.com/support/tools/gnss-planning/gnss-planning-17876.kjsp?RH=PRUFWMP
