An Inertial Navigation System (INS) is an autonomous navigation technology that primarily utilizes accelerometers and gyroscopes to measure motion states, thereby calculating the carrier's three-dimensional position, velocity, and attitude information in real time. Independent of external signals, this system offers the advantage of high-frequency output of motion parameters and is capable of providing complete six-degrees-of-freedom (6-DOF) data—comprising three translational components and three rotational components. Typically, an INS consists of an inertial measurement unit, a computer, and a control display unit; it calculates velocity and position data based on the measured acceleration signals.

During the manufacturing process of an INS, a turntable is required to calibrate its accuracy. Furthermore, certain products must undergo high and low-temperature testing, aging tests, vibration tests, and similar procedures to ensure that all performance specifications meet the required standards. The standard equipment configuration for the production line includes: dual-axis temperature-controlled turntables, dual-axis electric turntables, high/low-temperature (aging) test chambers, vibration test benches, shock test benches, and similar devices.

Moreover, the production line must incorporate automated and intelligent features to enhance both production efficiency and product quality.
