2-Axis Orbit Simulator

The input sine waves are acceleration signals in g. The top chart shows acceleration vs time. The left orbit is built directly from acceleration X and Y. The right orbit is built from displacement after converting acceleration using sinusoidal motion. The summary assumes the entered amplitudes are 0-to-peak g values from the accelerometers.
