A particle tracking system is being developed in the Particle Technology Laboratory of the Mechanical Engineering Department, at NJIT, In this thesis, an attempt is made to understand the effect of various parameters on the errors in the computed position and orientation of the sphere being tracked. Simulation results for a single transmitter assembly as well as a three transmitter assembly with 6, 9 and 17 antennae are presented. The effects of the level of noise in the voltages on the solution for the single transmitter assembly and three transmitter assembly are discussed. The concept of virtual antenna is introduced and experimental results as well as simulations results using the virtual antennae are presented. Simulation results showing the advantages of techniques such as perturbations and extrapolation in the solution code are discussed. The effects of antenna shape, size and aspect ratio on the voltages are studied, A new calibration technique for reducing the systematic errors in the measured voltages is proposed. The accuracy of the particle tracking system is confirmed by a test in which the sphere containing the transmitter is dropped in a free fall and the gravitational constant is calculated.
