Don't cut any thread yet, and position the GPS module next to FLORA.
Double check your knots again, adding a tiny bit more nail polish if any of them aren't staying tight. Once the nail polish is completely dry, you can cut your thread tails very short.
While the GPS doesn't have to be as close to FLORA as pictured to work well, it also shouldn't be too far away or the communication signal will degrade as the thread length increases. We recommend keeping them within six inches of each other.
At this point you can test the GPS the same way you did in the FLORA GPS guide, and verify your GPS is communicating with FLORA over the conductive thread!
Knot, seal, and snip the thread tails as in previous steps.
You can even use a safety pin to affix the gaff tape to the inside of the pocket, so it doesn't shake around when the dog runs.
We built the circuit right up top so you could see it better, but it would work just as well sewn entirely into one of the side pockets. The conductive stitching doesn't go all the way through the padded harness; it just pierces the top layer, so no threads are touching the dog's fur.
This circuit is not waterproof and should be removed from your dog before swimming or if it rains.
