I am still a little confused why 4 receiving LEDS are used and not 2, 1 for each beacon. ??

No, actually the tracking software uses just one beacon for tracking. The type that it tracks is selected using a switch on digital I/O 7. We use four receiving sensors for speed and it simplified the tracking algorithm significantly (I'm still writing the theory of operation).
