At present, when inertial navigation is installed on a three-axis turntable for testing, the installed three-axis turntable table top is a sunken circular groove, and the adaptive inertial navigation can only meet the installation requirement if the adaptive inertial navigation meets certain size and has circular appearance. Rectangular inertial navigation or inertial navigation of other shapes cannot be mounted in such a depressed circular groove because of the different layout of mounting holes, resulting in inapplicability of the test equipment. In actual work, a special fixed switching support is required to be customized according to the inertial navigation appearance, and the universality is lacking.
