There are lots of ways to set the tracker. I chose the highest possible resolution – one fix every second. You wouldn’t want to do this in real life, as it’s a little trying on the battery. For a short run, New Haven and back, it was just fine.
I am reasonably impressed. GPS is accurate to within a few dozen yards; fine for my purposes. Sometimes it puts you in the center median instead of the left lane. No big deal.
Sometime over the next few days, I’ll try mating it to photographs. For now, the attached map will suffice.
