High Precision Navigation System introduces the basic knowledge of inertial/satellite organization navigation system theory, optimal estimation theory and real-time error control method in navigation system.
The author has visited some universities and research institutes in Canada, the United States, Germany, France and other countries in combination with his scientific research work.In "High Precision Navigation System", some achievements of their research on key technologies of navigation system are introduced.As an example of engineering application of high-precision navigation system, the high-precision navigation system also introduces the accuracy assurance method of geodetic penetration measurement system in detail.
On the basis of the above research and interviews, the author proposed three engineering design methods for high-precision gyroscopes, including electrostatic, laser and optical fiber, including: (1) analysis of the overall structure;(2) Structure and process of key parts;(3) Error analysis, testing and model building;(4) Static and dynamic calibration of major errors in the navigation system.
The contents of High Precision Navigation System are engineering, practical and forward-looking.It has reference value for engineers and technicians engaged in research, development and application of high-precision navigation system, as well as teachers and students in colleges and universities.

In the 1970s, in the delivery vehicles such as nuclear submarines and long-range aircraftPlatform inertial navigation systemIt has been applied and become a model product for mass production.In a long voyage, they not only achieve the required positioning accuracy, but also can ensure the launch of weapons from the carrier.It can be considered that the successful application of ESG marks that the navigation technology has entered the era of high precision.
In the 1980s, laser gyro strapdown inertial navigation system was widely used in civil aviation aircraft, fighter aircraft, long-range artillery, tactical missile launcher and other carriers.Physically speaking, the optical gyroscope has no error related to acceleration, and its advantage is that it can start quickly without preheating and temperature control;The measuring speed range is not limited, and the linearity and stability of the scale factor are high.Therefore, compared with mechanical gyroscopes, optical gyroscopes have advantages in low cost and miniaturization. It can be expected that they will have further development.
