I would like to be able to setup a private GPS like settup.
Lets say I have a garden. I would like to setup 4-5 transmitters on a
post at it's corners.

Then I would like to have a box that would indicate it's position with
relative high accuracy
with respect to the transmitters.

Any ideas ?

RF based devices will cover a larger area at a not so high accuracy.
If the garden is not that large - or at the cost of more receiver
stations - you can use a modulated ultrasonic transmitter to attach
to the naughty kid and detect its position very precisely (at least
until the kid does not get naughty enough to get rid of the tag... :-)

Hmmm ... intersting application ;-) I'd like to be able to use it
indoors.
I am hoping to get half meter accuracy or better. The hints are a start
....

Any other takers ? :-)

What type of accuracy can be expected with ultrasonic ?
