RE: Wyze Lock Auto Unlock

The issue isn’t an Apple issue per se, it has to do with the antenna constraints on mobile devices. Apple Maps, Google Maps, etc. will all show this drift. Adding another antenna (not possible on most mobile devices) increases accuracy to ~1 meter horizontal, where the best you can expect from a single antenna or single frequency is ~3 meters, and is mostly greater than that. Buildings, trees, etc also cause inaccuracies in location, mapping programs become pretty much useless in places like Downtown San Francisco, for instance because of signal attenuation from the buildings.

There are some smoothing techniques that have been tried to the data provided by GPS, but that results in a tradeoff in accuracy while driving (as speed goes up, smoothing results in slower position updates).

I used to work on GPS-based systems up until 3 years ago…
