A few batches of the GS407 (uBlox) modules came defective. This problem includes units sold by SparkFun and DIYDrones Store ... The problem seems to be around the antenna solder joins, they are weak and break easily, so any little crash may break it. You can try to solder them by removing the hard glue, but is not recommended because you will void the warranty.
If you carefully check the picture you will see three tiny gold pins, those pins support all the stress and weight of the whole antenna. The big solder balls you see are mine, not from factory...
The uBlox chipsets are intact and fully functional but they are unable to catch satellites.
If you are a victim of this situation, please send it back to me and i will chip them out to the factory for a FREE repair!
Don't send me the remains of your module if you hard crash it, your burn it or something else is not related to this issue. Only units ordered from DIYDrones Store in good conditions will be accepted.

Honestly. I don't know... But if that happens after the firmware update.. well is mostly likely the new firmware...
Just after a little bit more hard landing I've upgraded ublox firmware to the latest version (6.02) and now I've got only about 8 satellites found in the best case. As i remember before upgrade it was about 12 but I don't know if it is not the case of the broken antenna joint.
Is it possible that after solder was damaged it still locks but with less satellites than before ?

What i can do is ask for complete saratel modules... The saratel modules is the big metal square (with the code bar sticker) attached to the bottom PCB that has uBlox chip mounted... Let me ask...
I was very disapointed with the unit quality and how loose the antenna became even without using or dropping the unit. I think u-blox should do a better job. It's not a cheap unit and should be a very stable and reliable one.
It should have a better structure and antenna fix, mainly because it is made to be a mobile device.
Also I did not think it's a very good receiver. My Iphone picks more satellites than the u-blox at the same place.
That's MY oppinion to the group.
Cheers,
Leonardo
