This work addresses the various stages involved in the development of a 3 dimensional tracking system based on ultrasonic transmitters and receivers. The hardware developed for this project can drive up to 24 ultrasonic transmitters and the receiver circuitry can detect signals from 8 receivers with high accuracy even in a noisy environment. Extensive experimentation has been done on the 1-D system and an accuracy of less than 1 mm was recorded except for certain points where the error is around 4.5 mm. This was due to one wavelength error in the time delay. A comprehensive calibration routine has also been developed for the system for easy and quick estimation of the receiver locations. The 3-D system was also tested and errors of up to 2.5cm were obtained.
