About once a month we get a phone call from somebody who wants a small GPS tracker. A really, really small one. Like, small enough to be sewn into a child’s clothing. That kind of small.
And they would also like to be able to watch the tracker update every second or so, in real-time. Oh, and, it can’t cost more than about $10 bucks. Usually, this phone call happens right after someone has seen a tracking device in a movie or a cop show. And while each piece of this is technically possible, putting it all into one single package is not, at least not yet.
Several factors determine the minimum size of a monitoring device. Let’s look at them one by one:

Location Tracking Method:
These days, there are multiple methods available to hardware designers when they want a device to monitor location. Here are just a few of the most common technologies in use:
Power Source:
All tracking devices must have some kind of power supply to two basic things; figure out where they are, and communicate that information when asked to do so. Here are three of the most common power sources:
Communication Method:
Once the device has been powered up and a location has been determined, that information has to be transmitted to the owner of the device. Some of the more popular methods are:
