Hi and thanks for your reply! Sorry I didn’t respond till now, I was away for a few days. Unfortunately I don’t have a hot air machine, and I’m not sure any of my past adventures in de-soldering and re-soldering qualify as “rework.”
It does look as though the GPS module is well integrated into the PCB. I wonder if that ceramic square is just the antenna, with the guts of the GPS spread out across the PCB.
I have to admit the job looks a bit intimidating… but that’s just because I don’t really know where to start.
