The inertial test turntables have a wide range of applications, primarily in high-tech and defense sectors:

1.Calibration:

Error parameter measurement: Inertial devices (especially gyroscopes and accelerometers) exhibit various errors, such as scale factor error, zero bias, and installation errors. Turntables provide known, precise angle, angular rate, or angular acceleration inputs, allowing engineers to measure these errors. This allows for software compensation in subsequent use, improving navigation accuracy.

2.Performance Testing: 

Threshold Testing: Tests the minimum angular rate (resolution) that the gyroscope can sense.

Dynamic range test: Tests the device's working performance at extremely high and low angular rates.

Bandwidth Testing: Tests the device's responsiveness to rapidly changing angular rates.

Environmental Testing: Tests the device's performance stability under environmental changing conditions such as temperature and vibration.

3. Functional Verification:

Simulates realistic flight, navigation, or motion attitudes (e.g., pitch, roll, and yaw) for the entire inertial navigation system (INS) or attitude and heading reference system (AHRS). By comparing the actual values ​​output by the turntable with the measured values ​​from the inertial system, the correctness of the entire system's algorithms and functionality can be verified.

4. Simulation:

In hardware-in-the-loop (HIL) simulation, a turntable can simulate the motion of aircraft, missiles, satellites, vehicles, allowing the navigation system installed on it to "believe" it is operating in a real-world environment, thereby enabling full system testing and verification.
