A comprehensive system to track a particle non-intrusively in three dimensions is currently being developed based on the principle of magnetic induction coupling. The system consists of one or more small transmitters, powered by small batteries, mounted inside the particle and six or more receiving antennae which acquire the induced voltages. An important part of the system is to derive a position and orientation from the voltages induced in the antennae. This is the focus of this paper.The feasibility of the proposed technique is established through simulated and actual experiments. Practical issues such as the effect of signal noise are considered. The technique presented here has a wide range of applications due to its non-intrusive nature, and is particularly useful when optical techniques are not feasible. Directions for future work are discussed.
