Inertial navigation systems usually include sensors such as accelerometers and gyroscopes, which are used to measure the acceleration and angular velocity of objects and make continuous estimates through computers to determine the position, attitude and speed of moving objects. Inertial navigation testing usually requires a special test platform, which is designed to provide accurate environmental simulation and test conditions. In the process of inertial navigation testing, the existing test platforms need to turn at multiple angles, which will cause the bottom structure to loosen and produce gaps over a long period of time, affecting the degree of inclination above and reducing the test stability support performance.
