The Importance of INS

Inertial technology is one of the key technologies for navigation of carriers. Inertial technology is a technology that uses inertia principle or other relevant principles to independently measure and control the motion process of a carrier. It is inertial navigation, inertial guidance, inertial measurement, and inertial sensor technology. The general term. Modern inertial technology, supported by the abundant funds of governments in various countries, has penetrated into civil use from the initial military applications. Inertial technology plays a very important role in the defense equipment technology. For medium- and long-range guided missiles that are inertially guided, generally speaking, the accuracy of hitting 70% depends on the precision of the guidance system. For missile-based nuclear submarines, their position and speed change due to long submergence time, and these data are the initial parameters for launching missiles and directly affect the accuracy of missiles’ hits. Therefore, they need to provide high-precision position, velocity, and vertical alignment signals. The only navigation device currently available for submarines is the inertial navigation system. Inertial navigation relies entirely on the carrier’s own equipment for independent navigation. It does not rely on external information and has the advantages of good concealment, work-free weather conditions and human interference, and high precision. For long-range cruise missiles, the inertial guidance system, coupled with map matching or other guidance technology, can ensure that it can still hit targets with high accuracy after a few thousand kilometers. Inertial technology has been gradually extended to aerospace, aviation, navigation, petroleum development, geodetic survey, marine survey, geological drilling control, robotics, and railways. With the advent of new inertial-sensitive devices, inertial technology has been applied in the automotive industry and medical electronics. Equipment has been applied. Therefore, inertial technology not only occupies a very important position in the modernization of national defense, but also shows its tremendous role in various fields of the national economy.
