How do you quality check if a GPS module and its subsystems are up to the mark during manufacturing? My company recently had issues with few of its devices. Some weren't having a GPS lock (ever) and the issue was found to be the antenna (once replaced it worked fine).
But we can't test every device (over 5000) for a GPS lock during manufacturing (or is that the only way?). Is there a standard way to check to make sure the hardware won't let us down?
Edit: Can I assume the hardware is fine if I receive a valid data time (a data time other than the default one send by the hardware)?
Answer
That is, no contact. I've currently come across 2 cold soldering and 3 no contact issues.
Looks to me you have got a hole in your final testing. (I assume you have some sort of test-jig)
I can imagine that waiting for a GPS lock requires too much test time but, especially with the detected errors you should add a resistance/contact/SWR test on the antenna.
