Inertial navigation system for sounding rockets and launch vehicles

Inertial navigation system (INS) is an autonomous navigation device. It completely relies on the equipment on the carrier to autonomously determine navigation parameters such as the heading, position, attitude, and speed of the carrier, without the need for any external light, electricity, or magnetism. And other information, can provide the carrier position, attitude, speed and other information in a continuous and real-time manner; it is not dependent on external information and is not affected by climatic conditions and various external interference factors.

Inertial navigation system (INS)determine navigation parameters such as the heading, pitch roll

The inertial navigation and control system was originally mainly used by aerospace, ground, and maritime military users. It is the core technology product of modern defense systems and is widely used in defense fields such as aircraft, missiles, ships, submarines, and tanks. With the reduction of cost and the increase of demand, inertial navigation technology has been extended to commercial fields such as geodesy, resource survey, geophysical survey, ocean exploration, railway, tunnel, etc., and it is also widely used in robots, cameras, and children’s toys.

The purpose and method of using inertial sensors in different fields are roughly the same, but the emphasis on device performance requirements varies. From the perspective of accuracy, the aerospace and marine fields have high requirements for accuracy, and their continuous working time is also long; from the perspective of system life, spacecraft such as satellites and space stations have the highest requirements, because they cannot be replaced or maintained after launch; guidance weapons It has the shortest system life requirements, but may need to meet the requirements of long-term combat readiness. Involved in military applications and other fields, the reliability requirements are high.
