The present disclosure relates to an inertia measurement unit for an unmanned aircraft, which comprises a housing assembly, a sensing assembly and a vibration damper. The vibration damper comprises a first vibration-attenuation cushion; and the sensing assembly comprises a first circuit board, a second circuit board and a flexible signal line for connecting the first circuit board and the second circuit board. An inertia sensor is fixed on the second circuit board. The inertia measurement unit further comprises a weight block, and the second circuit board. In the present disclosure, components including the inertia sensor and so on that require a high vibration performance are integrated on the second circuit board, and by disposing the first vibration-attenuation cushion, vibrations suffered by the inertia sensor are attenuated to below 30% of those suffered before the vibration-attenuation cushion is disposed. This greatly reduces the influence of the operational vibration frequency of the unmanned aircraft on the inertia sensor and improves the measurement stability of the inertia sensor.
