How do you get 'direction' - the satellite is always directly above your head.
No, you need to read up on triangulation and ponder it a bit.
On a flat surface you need a minimum of three references. Inside a sphere I think you can get away with four.
I think you can get away with three - assuming you don’t care about altitude.
They’d not be symmetrically positioned, so some areas of the surface would have lower accuracy thannothers
