The project is to locate a r/c boat in a roughly 2 to 3m^2 water
filled box, hence the transmitters or recievers will only be on the 3
or 4 walls of the box.

It will need to be fairly accurate considering the size of the box
relative to the size of the boat (i.e down to cm's).

We are also considering placing a webcam above the box and using image
processing to locate the boat, however I thought we might get more
accurate results using RSSI.

I hope that helps.
