For <27 that would be for a warm start from previously having a fix… and if no power is lost to the GPS. (this is why there is a superCap included which should last for 1-2 hrs proving battery backup to the GPS.)
It usually takes between 10-30 mins for first time to fix.
We test every unit to see that data is received over serial. We then test every 10th for GPS, using an external antenna.
Can you share a close up photo of the top half of the board, i want to make sure nothing is missing
