Inertial Navigation System Importance

Inertial technology is one of the key technologies for navigating the carrier. Inertial technology is a technology that uses the principle of inertia or other related principles to autonomously measure and control the motion process of the carrier. It is inertial navigation, inertial guidance, inertial measurement and inertial sensor technology. The general term. With the support of the strong funds of various governments, modern inertial technology has penetrated into the civilian sector from the initial military application. Inertial technology plays a very important role in defense equipment technology. For inertial guided medium- and long-range missiles, the hit accuracy of 70% is generally determined by the accuracy of the guidance system. For missile nuclear submarines, their position and speed are variable due to long snorkeling time. These data are the initial parameters of the missile launch, which directly affect the missile’s hit accuracy. Therefore, it is necessary 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 to navigate independently and independently, without relying on external information, and has the advantages of good concealment, work without weather conditions and human disturbance, and high precision. For long-range cruise missiles, inertial guidance systems plus map matching technology or other guidance techniques ensure that they can hit targets with high precision after flying thousands of kilometers. Inertial technology has been gradually extended to aerospace, aviation, marine, petroleum development, geodesy, marine survey, geological drilling control, robotics and railways. With the emergence of new inertial sensors, inertial technology in the automotive industry, medical electronics The application is available in the device. Therefore, inertial technology not only occupies a very important position in the modernization of national defense, but also shows its great role in various fields of the national economy.
