Inertial navigation test equipment and motion simulation test equipment are both characterized by multi-axis motion, so they are referred to as turntables for short.
The inertial navigation test turntable system mainly provides accurate spatial coordinate positioning, precise angular rate and angular acceleration test benchmarks for the performance test of inertial components or navigation systems; the motion simulation turntable can generally be divided into the flight motion turntable and the target motion simulation turntable.
It is used to provide realistic carrier posture and target tracking motion simulation environment.

Inertial instrument is an extremely precise instrument.
It refers to a gyroscope characterized by the inertia of a rotating mass and an accelerometer characterized by the inertia of a translational or rotating mass in the inertial technology.
Gyroscopes and accelerometers are indispensable core measuring instruments in inertial navigation systems or inertial guidance systems, and inertial measurement devices are composed of them.
Among them, the gyroscope is used to detect the angular movement of the vehicle in the inertial space, and the accelerometer is used to detect the specific force when the vehicle is moving.
Inertial navigation test equipment is a tool for evaluating inertial instruments.
Without high-precision modern testing equipment, it is impossible to evaluate the actual working performance of the inertial instrument and determine whether it can be used, and it is impossible to provide a sufficient and reliable basis for improving the design and error compensation.

The research and development of Russian centrifuges has also been carried out very early.
The main research and development units are the Mendeleev Institute of Metrology and the Moscow "Rotor" scientific research and production consortium.
The centrifuges developed in Russia are mainly divided into blue types: one is the centrifuge that produces constant acceleration; the other is the centrifuge that can produce both constant acceleration and harmonic acceleration with a reversing platform; the third is a centrifuge with a tiltable spindle Centrifuge.
The Mendeleev Institute of Metrology has a number of Russian national metrology standards, such as length benchmarks, mass benchmarks, and gravity benchmarks.

The development prospects of centrifuges
The development prospects of centrifuges In summary, the development of domestic centrifuge technology started late, and many production technologies rely on foreign imports, and the development speed is very slow.
Although in recent years, with the support of national policies, scientific research institutions have accelerated the pace of centrifuge technology research and development, the centrifuge companies themselves still invest little in centrifuge technology, and the innovation of centrifuge technology is slow.
The gap is still large.

With the rise of the Chinese centrifuge brand, the enterprises that represent the good technology of centrifuges have accelerated their pace of entering the world trade, and the trade trend of centrifuges has become more and more rapid.
This is due to our innovation in centrifuge technology.
Experts predict that the centrifuge will have a major change in the next five years.
The main change is not in technology, but the integration of market size, market sales system, management system and other aspects.
