Abstract

The invention relates to a method for improving the precision of a pendulum gyroscope north seeker based on the improvement of a reference mirror process, which comprises the following specific steps: 1, manufacturing a mirror surface structure at the upper part of a gyroscope frame, and primarily processing the mirror surface structure integrally formed with the gyroscope frame; 2, conducting polishing treatment on the mirror surface structure subjected to primary machining in the step 1; and 3, the mirror surface structure polished in the step 2 being subjected to film coating treatment. According to the invention, the manufacturing process of the reference mirror is improved from a gluing process to a process of directly carrying out precise turning, milling, grinding, polishing and coating treatment on the metal structure substrate, so that the structure of the reference mirror is simplified, the assembly process flow is simplified, and the assembly production efficiency is improved.
