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)?
