There was a motion sensor made for the PSP... It's just not official. It was made by the PSP homebrew community, so it's not compatible with anything except homebrew games.

Can anybody enlighten me why PSP needs a GPS unit?
What it does add to games?
I can understand (and would appreciate) touchscreen. Or motion sensor. But GPS?

Is the reason so obvious that it confuses you? It's not about games. A GPS tells you where you are.
You can either carry around both a regular GPS unit and a PSP or just a PSP that does the job of both. Think about it.
