New specification for dual-axis temperature-controlled inertial calibration systems covers turntable accuracy, thermal performance, and timing modules. Supports autonomous driving, UAV, and precision manufacturing testing needs.

A simulation turntable is a high-precision ground-based simulation test equipment. Its core function is to replicate, in a laboratory environment, the attitude motions and dynamic characteristics of airborne vehicles such as aircraft,, and satellites. By accurately reproducing angular motions including pitch, yaw, and roll, it provides the device under test with a realistic dynamic testing environment that closely approximates real flight conditions.

In inertial navigation, aerospace, and precision weapon testing, the initial azimuth alignment of a turntable directly determines the validity of subsequent test data. North-seeking – i.e., determining the angle between the turntable zero line and true north and then nulling it – is the “first procedure” before putting the turntable into service. Based on engineering practice, this article systematically describes the standard operation workflow of the FOG/RLG gyro north-seeker method.
