Abstract
An American football is tracked using a long-range magnetoquasistatic position and orientation measurement system. A low-weight emitter that emits a low-frequency quasistatic magnetic field is embedded within an American football. The emitter weighs a total of 26.5 g, which is within the manufacturing tolerance of an American football and does not alter the dynamics of the ball. Measurements of a person carrying the football along the goal line of an American football field is described, along with a description of the construction of the magnetoquasistatic tracking system. The technique demonstrates measurements with a distance accuracy of 15 cm and an azimuthal orientation accuracy of 2.45◦ for measurements conducted along the goal line of an American football field.
