Background
The gyroscope is an angular motion detection device which uses a momentum moment sensitive shell of a high-speed revolving body to rotate around one or two axes orthogonal to a rotation shaft relative to an inertia space. The gyroscope comprises an accelerometer, an angular velocity meter and a magnetometer inside, the accelerometer and the magnetometer are susceptible to vibration noise, and the angular velocity meter can drift due to integration, so that measurement errors are generated. In order to correct the measurement errors, the values derived by the accelerometer and magnetometer need to be data fused by an algorithm. However, further verification of the gyroscope is required after data fusion to check the adjusted gyroscope measurement accuracy.
The conventional gyro three-axis turntable for verifying the measurement accuracy of a gyro has the following problems: 1. the traditional gyroscope three-axis turntable is not provided with a level meter, and an additional level meter is needed to adjust the angle of the platform during installation. 2. The structure is complex, and the maintenance cost is high (such as bearing and motor replacement are difficult). 3. The rotary table which adopts manual rotation has relatively low price, but the operation is not convenient enough and the measurement error is large.
For the above problems, some researches have been conducted. For example: chinese patent No. CN201410221836.4 discloses a top characteristic demonstration device, the top rotor is fixedly connected with the rotation shaft of the driving motor, the driving motor casing is fixedly connected with the inner frame, the outer frame and the base are respectively connected through the rotation shaft, the inner frame and the outer frame are respectively provided with round holes, the rotation shaft of the inner frame and the outer frame is provided with elastic pressing sheets and pointer lines, the two sides of the outer frame and the base are respectively fixedly connected with a power supply slip ring and an angle dial, and the motor is connected with a power supply line through the slip ring.

Chinese patent No. CN201420812409.9 discloses a gyroscope automatic test equipment, which is composed of three rotating mechanisms and a data transmission mechanism, the rotating mechanism includes a rotating shaft, a bracket and a power device for driving the rotating shaft to rotate.

Although the two patents adopt driving devices such as a motor and the like to enable operation to be more convenient and reduce measurement errors to a certain extent, the initial position cannot be directly adjusted due to the fact that the initial state detection device is not arranged during equipment installation, and additional level adjustment is needed, otherwise, the verification result is affected.
