Abstract

The invention provides a method for improving output precision of a gyroscope, comprising the steps of assembling a plurality of gyroscopes in the same direction; leading the gyroscopes to work; sampling the output signals of the plurality of gyroscopes and respectively obtaining the corresponding angular speeds; obtaining the angular speed median; calculating the average value of the angular speed; calculating the average value of the angular speed median; calculating the standard difference of the angular speed; calculating the standard difference of the angular speed median; comparing the minimum value of the angular speed standard difference with the standard difference of the angular speed median; and judging whether the precision of the gyroscope is improved or not. The method has the advantages that the method is simple and convenient; the method can improve the precision of the gyroscope by adopting the redundancy design of the gyroscope; the operating method is simple and feasible; the principle is reliable; according to the definition of the standard difference in the mathematics, the method has complete theoretical supporting and obvious effect; and according to the output date chart, the precision comparison can be seen clearly, and the effect is extremely obvious.

Description

technical field [0001] The invention relates to a method for improving the output precision of a gyroscope. Background technique [0002] Gyroscope is an instrument that can accurately determine the orientation of moving objects. It is an inertial navigation instrument widely used in modern aviation, navigation, aerospace and national defense industries. Its development is of great importance to a country's industry, national defense and other high-tech development is of great strategic importance. [0003] In recent years, with the development of MEMS (Micro-Electro-Mechanical Systems) technology, the research and development of MEMS gyroscopes has received extensive attention. MEMS gyroscopes have the advantages of small size, light weight, good reliability, and easy system integration, and have a wide range of applications. However, the accuracy of the MEMS gyroscope is not very high at present, which affects its usability. The main reason is that the output signal inte...
