Shielding worked for me! However it took 5 revisions to get it right!!!
Here is what I did to discover and resolve the issue.
1. It's definitely a shielding problem between the GPS circuit and main board components. ( This was confirmed by removing the top shell, and placing away from the main board while ground testing... No loss of sats when record was on).
Sooooo.. I knew shielding would resolve if done right.
2. I first, pealed back the installed factory shielding half way and bured the gps connector cable, as stated and shown in the discussions above.
3. I then installed additional aluminum tape shielding over that, and covered the exposed metal surface with thick clear gorilla brand packing tape. (This has also been shown in the discussion). While this helped a bit.. loosing now only 2 sats instead of 4, it did not eliminate the problem.
4. Next, I made an open "box" out of 4 layers of aluminum tape with 1/8" sides to completely cover the components over the main board. The box was also covered in gorilla tape to insulate the metal so that nothing would short. Better, only loosing 1 sat at this point when video recording on.
5. The key factor.... Cover the GPS connector lead ALL the way to the connector with the metal tape covered with the gorilla packing tape.
6. reassemble.... No loss of sats at all when recording.
This took a lot of experimentation and revisions to get right, as when the shell is closed, the space between the gps and the main is really close.
Like I said, It looks like a definite shielding, (or lack of) problem ... Had the above not worked... I was going to buy a new shell and modify it to put the gps circuit on top of the model.
Hope this helps out someone, let me know if you get it working using this method!
