Two-dimensional trajectory analysis of a point mass circular movement gyroscope, fabrication of a macro model of the gyroscope, and measurement of its characteristics, have been carried out. The gyroscope consists of a point mass on the tip of a pillar which moves in a circle, and sensors which detect displacement of the point mass caused by Coriolis force. The trajectory of the point mass was indicated in an oval shape, which was symmetry to an axis, an external rotation rate applied. Deviation from circular trajectory of the point mass was indicated as a function of external rotation rates applied around the <i>X</i>-axis ω<i><sub>X</sub></i> and the <i>Y</i>-axis ω<i><sub>Y</sub></i> and of a time <i>t</i>. In the macro model, the point mass was given a steady circular movement by electromagnetic actuators. Displacement of the point mass caused by Coriolis force was detected with piezoelectric sensors which were attached to a beam supporting the pillar. Resonant frequencies of the <i>X</i>-axis and the <i>Y</i>-axis were 130 Hz±4 Hz. An output sensitivity of 4.2mV/p-p to 2.5deg/s was obtained.
