1. A method for generating a beacon signal to be used in determining a position and/or orientation of an object, the method comprising:
causing a first coil to generate a first magnetic field and a second coil to generate a second magnetic field, wherein the causing comprises:
providing a first signal waveform that is binary, and has a fundamental harmonic frequency, to a first driver and controlling the first driver to provide a first electric current to the first coil and a first capacitor in series with the first coil using the first signal waveform, a series combination of the first capacitor and the first coil exhibiting a resonant frequency, wherein the fundamental harmonic frequency is different from the resonant frequency;
providing a second signal waveform that is binary to a second driver and controlling the second driver to provide a second electric current to the second coil and a second capacitor in series with the second coil using the second signal waveform; and
with an activation circuit, providing a supply voltage to the first driver that increases over time.
