No your post was very misleading so it was garbage as far as I was concerned, if your going to post information make sure its accurate and yours was not.
I'm with you Mike. I've worked with GPS, Land, Marine, and Air long enough to know what it takes to get a good 3D, not 2D lock. 12.5 minutes is just from an initial cold start of a GPS or if the GPS has sat unused for 20-30 days, subsequent flights, within 1-3 days should 3D lock in under a minute. I've talked about 12.5 minutes and why it's important but won't get into why satellites transmit navigation data at 50bps or the engineering tricks newer GPS receivers use to decrease cold start time. The problem is that some people take offense to good advice from people with many years of experience gleaned from many costly mistakes. Not sure why that is. That's fine, no one is making anyone do anything, we're just trying to help and save you some bank, take it or leave it. But if you complain about waiting and have a fly away, don't come here whining and belly aching, or blaming the manufacture, suck it up and chalk it up to one of those costly mistakes. Waiting 12.5 minutes whether summer or winter makes no difference to me. I've lived in Michigan my whole life, winter is just a season, camping in the middle of winter in a tent in sub zero temperatures in 5' of snow changes a person. Maybe its bumping the side of the tent and feeling it snow which is nothing more than my frozen condensed breath falling from the inside of the tent. I just have to remember to keep my batteries warm in my sleeping bag before I go flying.
Yes you definitely have a point! have you by chance tried both ways of updating the H firmware? Maybe one or the other give you better result. I'm saying if you only have ever updated your H by downloading the firmware & then put it onto your SD card then into your gimbal maybe try updating it by connecting it to your computer with a USB cable via the GUI!! Hope you all the best of luck with this & can get it fixed without having to send it back to Yuneec!! Otherwise all I could think of is to try a different SD card, First format your SD Card, try to do the whole process using a different computer (Just in case you may have a virus & not know about it that is affecting your firmware update) & literally I think after trying all those along with everything you have already tried I think that the only other possibility is literal MAGIC!!!!! I'd still personally like to know whether others that also have similar problems as you do, have ST16's & H's that are by any chance built during the time frame or at the same assembly location, or by chance if it's possible to find anywhere whether it be documentation you have, possibly by decoding the serial # or MAC Address, or somewhere digitally on your ST16 that you can find a Build Batch # (IE just like with other products if they possibly make or assemble the H's in Batches)
It has been posted here and other forums regarding the time for GPS lock. If the GPS unit is turned on in the vicinity it was last used and within a few days, the lock will occur in a few minutes. If it is started hundreds of miles from the last use then it will take several minutes. If it is a new GPS or if the unit has had a firmware update (which erases the last position) then it can take up to 12.5 minutes to get a full lock.
Unfortunately GUI woun't connect to H. Windows 10 saying can't recognize device or something like that.. SD card is new, formated and this is the same card used when i installed firmware 2.21 and then 2.25 and then again to 2.21. So I don't see problem here. PC does not have viruses or whatever, Bitdefender is watching.
I'm aware of what UTC is Mr Graham. I have had a pilots license for many years... But thank you for presuming that I didn't know!
It has been pointed out by a number of people that that video is quite misleading. The 'GPS Used' true/false column is *not* GPS Lock.
