What is the smallest GPS tracker?

Question

satellite navigation

Hey!
Tell me, what small GPS trackers exist so that it is possible to embed them in a child’s clothes, in a cat’s collar or, for example, in shoes?
Of all that I was looking for, I found StickR TrackR
This, of course, is a cool model, but it can be torn off. Looking for something smaller

Answer 1

TrackR does not have GPS. They just mislead everyone.
The technology they "invented" is called Crowd GPS . TrackR is a regular iBeacon. Its broadcast packet is received by the mobile application and sends its coordinates to the server with the identifier of the received packet. The idea is interesting, but it's not GPS.
There are no such small trackers as you want yet. Batteries take up a lot of space. The efficiency of the antenna is also strongly dependent on the dimensions (the larger the dimensions, the better). If you want a reliable proven solution, use Meitrak or Queclink. Well, or any other proven Chinese.

Answer 2

Take two. This one and more. The big one will be plucked, but this one will not be looked for.
There is nowhere less.
