I'm currently working on a project to put a gps chip on a keychain to track keys if they are lost, but I don't have a lot of experience with gps and would appreciate some outside expertise.
We want to be able to use a smartphone to track the position of the keychain, but we are wondering if it is even possible for the receiver on the keys to send that information to the phone. Basically can the chip be tracked externally, or are the gps coordinates only useful for the keychain to locate itself (if that makes any sense)?
We've also been trying to do research on which components we need in this system, but so far the only information we've found is how the receiver communicates with the satellites to determine its location. We don't really understand how the receiver then decodes that information or how it transmits that information in a way that is meaningful to a user.
We assume we need a receiver obviously, and also an antennae and some kind of power source, but what other components might we need? Would we require some kind of onboard microcontroller to carry out other functions?
Any help you guys would be able to give on this project would be greatly appreciated, and thanks for your time.
