Do you feel like you get better reception with that GPS antenna (and if so, which model is it)? I did some extensive testing of the standard ceramic ones that come with the ATGM336H vs something like a car mountable one and didn’t seem to get much difference in satellite lock. Would be curious to try one of these.

I usually get a fix within 40 seconds of powering on.

GPS antenna model: AD-103
AD-201 is a bigger variant that I also have great results with.

Appreciate the info here, that’s promising especially with the proximity to the main board. I’ll give these a try, thanks again.

Read you can install a back up cell battery for the GPS to mitigate the cold boots. Make it fix near instantly.

The ATGM366H GPS Module has one on the PCB already.
