I think the project is doable, but your requirement list is pretty long.
Both Adafruit and SparkFun have tutorials on GPS modules for use with
Arduinos and Raspberry Pis.

I'd start by doing a bunch of reading and research, and maybe buying a
few parts to experiment with. This might give you some idea of what is
possible. There's going to be a lot of code needed as well, obviously.
