Ultrasound 3D positioning

How would you use an array of ultrasonic sensors to determine the 3d position of an ultrasonic transmitter.

Basically i want an ultrasound transmitter on my hand that gets picked up on an array of 5 or so receivers that outputs the position via usb.

That should be basic triangulation. You know the fixed distance between where you mount the two separate receiving sensors. If they can determine the range to the target from each, that gets plugged into simple geometry formulas. You can then figure out the relative coordinates.

They do have ultrasonic rangefinders and ultrasonic measuring tapes. Look up the design for them. I don't know how accurate you need it to be or what range you are looking at. Good luck.
