摘要
Abstract
Since the 1950s,inertial technology has gradually occupied a dominant position in the field of navigation.In the integrated navigation system since the 1980s,inertial technology is still dominant.However,inertial navigation technology has been troubled by setting initial values and decreasing accuracy over time,and its price is high.The gap between the spherical rotor and the bowl electrode is very small.The supporting high pressure is added between the electrode and the rotor to form a strong electric field between the electrode and the spherical rotor.When the electrostatic force of the spherical rotor is balanced,the spherical rotor will be supported.Through the quantitative analysis and single test of ESS rotor displacement measurement circuit error,the separation method and results of each component in the total drift error are described.On this basis,the methods and ways to improve the precision index are summarized.The fully shielded and modular circuit is developed and loaded into the gyroscope body.关键词
