navigation - What can I do when my GPS doesn't work (or if my tablet doesn't have GPS)?

The problem: I want to use an (offline|online) navigation app but:

• I have an Asus Transformer Prime with very bad GPS reception


• I have a tablet without GPS (e.g., a Nook Color)



• My phone has a very low GPS signal
  (Samsung is infamous here, Galaxy S, Nexus S, Gio and so on all have users complaining about it)


• My phone often loses track of GPS satellites

My device has Bluetooth however.

What can I do to get a working and precise GPS signal?

Answer

I have several bluetooth-GPS adapters that I use with all of my devices when I need a superb signal because a specialiced receiver is almost always superior to a smartphone's internal GPS (due to integration constraints).

It's very handy for my Nook Color tablet that has no GPS but bluetooth (Asus Transformer Prime users also have this kind of problem).
