My bad, thanks. I'll try it.Re-read post 27. Its all in this thread.
Continued good luck getting to the root cause!

I found this picture of what I guess is the FC Board. Is it plugged in by a cable or pins on the board? I think I'm pushing my luck every time that I take the cover off. Thanks.@PSUTEX,
I've attached a "summary" of the things I see in the Flightlog data. The summary itself is something of a bear to digest. From what I see, here is what I suggest:
1.) Remove the top shell and clean the contacts on the FC Board. It just unplugs, but be sure to align the pins carefully when re-installing. It will plug in one pin off, but it will not work that way, of course.
2.) Take it to the cornfield. I don't think you will get GPS at home.
3.) Try it with the NEW controller first.
4.) Try it with the OLD controller.
5.) If either controller works at the cornfield, then try it at the house.
If nothing works, it becomes an Easter Egg hunt. I would suggest:
a.) New FC board.
b.) New RF module in the drone.
c.) Maybe at least find someone with a known good ST16 to try.
The recommendation for the cornfield is because the data never clearly shows success at the house. If it has happened, that would be good to know.
The recommendation to try another ST16 is because the "NEW" ST16 has some ambiguous performance indicators in its history.
The recommendation to try the "OLD" ST16 comes from the first attempt you made after replacing the GPS module. You were using the "OLD" ST16. You let it have about an hour to acquire, but it never did. What you could not see was the readings were getting steadily better during that hour, and were still improving. This is not uncommon for a new GPS unit, or a KIT that has been in storage. It is POSSIBLE, (not certain) that had you shut down and immediately tried again, you may have achieved GPS acquisition.
Another observation was that the troubles began at the end of a flight on September 06, 2019 at about 4:30 in the evening. I can't tell what happened yet. That will take more study. If you recall anything about that flight, it would be helpful.
@DoomMeister, is correct. The double row of pins down both sides is what holds it on. Just unplug the connector wire, and start rocking, pulling and a little prying, it will begin to work off the board.I found this picture of what I guess is the FC Board.

Great. Thanks a lot.@DoomMeister, is correct. The double row of pins down both sides is what holds it on. Just unplug the connector wire, and start rocking, pulling and a little prying, it will begin to work off the board.
Alchohol and an old toothbrush will work. Some Contact Cleaner would probably be better, but alcholol will do fine.
Be sure to carefully line the pins back up when you put it back on. It's possible to get it a pin or two forward or backward, and that will cause an issue. You will be able to see enough to get it right.
Those two tests sound good. I will do that. One thing slowing me down is a suggested no unnecessary driving in my county by the governor of PA. Unless I'm on my way to the grocery store I won't be using the corn field. I can walk to a park near me. The issue with this park is it only 400-500 feet from high tension power lines. Don't know if that far enough. Last night before reading this I created a new model on my original ST16 and bounded it to the H.Next step would be to remove the battery from the ST16, wait 10min and put it in again to provoke a complete cold start of the Android.

Thanks for looking at this. I did a compass and accelerometer calibration at the flight spot. Becasue of limited driving I walked to a park thats about 400 feet from high tension power lines. I wasnt sure if this was too close. I didn't even have a sun shade on for this flight. So the antenna is under the ST16 top cover parallel to the screen above where the micro SD card is? I didnt have anything but maybe my hands or body blocking the view to the sky.flight #00027: Compass Calibration Warnings longer than 3s will be reported as message at ST16 and the drones status LED (the back light) will flash orange. The compass warnings are in the flight log. Compass errors will result in some erratic flight behaviour.
Please do a compass calibration in open area without magnetic influences (power lines, mobile phone, iron bridges and so on are bad). Also I would calibrate the accelerometer.
The gps-used flag is oszillating during initialization again due to controller GPS. In-flight it was OK.

The GPS-Antenna of the ST16 is somewhere near the SD card slot. Do you have obstacles there that block the direction to the sky? A tray or sunshade or something like that?

I looked at your graphic of the analyzer and even with your notes don't understand it. I will try and read the manualthat youcreated. In short what do you think is my problem or what should I try? I'm going to try using my other ST16 next unless I hear differently.
