Motion Simulation for Qualifying Gyroscopes
Multiple Degrees of Freedom – Highly Dynamic Following of Predefined Trajectories
Gyroscopic instruments, i.e. gyroscopes, can detect and measure a rotary motion or acceleration of the external reference system in relation to the rotating mass. For example, built into theodolites they are used for precise measurements in geodesy, mining, or geology. Due to their properties, gyroscopes are also used for active attitude control in aerospace and marine applications. The ISS space station, for example, uses the gyrocompass to determine its position in space. Even many smartphones have a built-in gyrocompass for navigation and location.
In order to qualify gyrocompasses, real conditions such as ship movements must be simulated. ISO standards exist that describe the motion profiles and performance requirements in detail for these test procedures. The combination of reaching a target position with a certain precision and the translational and rotational movements (roll, pitch, yaw) is a challenging task that can be performed by specifically designed hexapods.

Further Industries and Applications that Benefit From Motion Simulation with Hexapods
Freely Definable Center of Rotation
The freely definable rotation or pivot point is an essential feature of the parallel-kinematic hexapod. This means that the motion of the hexapod platform can be specifically adapted to the position of the gyroscope so that ideal realistic conditions can be created.
