Hello Adafruit Community.
I'm struggling to get performance from our FGPMMOPA6H GPS module which we have mounted to our custom PCB. We really liked the performance of this chip when we used it as a breakout board, however, when we mount it to our PCB the module is unable to find a fix.
I was hoping to check in with the community and see if others had successfully mounted this module to their designs and if they had any problems like the ones we are having.
I am also interested in people's thoughts on our use of ground plane below the chip. We did this to isolate it from noise, but its so different from the original breakout board, I am concerned we inadvertently messed up one of the features.

Thank you for your help!
Adafruit mounting. These board work wonderfully! However, they have traces going directly under the module!
Our way of mounting to the PCB. Notice the large ground plane (Purple). We thought this would improve performance, but maybe we've made it worse by doing this?
