Solar Jetman item

In Games

I have a doubt since ten years ago!! There's an item in Solar Jetman, at the bottom of planet 2, it looks like a star; when it is picked up, the game says that the player is equipped with "navigators", but I still don't know what is it used for!! Do you?

I did a Google search and found this document. It seems that it's a free map? I'm not sure how the game works, having never played it, but that's what I got out of this.
