Method and system for testing an alignment model of a submarine-launched missile inertial navigation platform

Abstract

The invention relates to a method and a system for testing an alignment model of a submarine-launched missile inertial navigation platform, and relates to the technical field of submarine-launched missile launching. The method is applied to the alignment model test system of the submarine-launched missile inertial navigation platform. The alignment model test system of the submarine-launched missile inertial navigation platform includes a terminal, a swing table controller, a swing table, a dynamic angle measuring device, and an inertial navigation platform simulator. In the embodiment of the present invention, the swing table controller controls the swing table to work, so that the swing table swings according to the set vertical and horizontal frequencies to generate pitch angle and roll angle information; start the stepping motor controller, and the stepping motor controls The controller controls the stepper motor to be in the tracking working state; the terminal conducts a semi-physical simulation test on the alignment model to be tested according to the alignment operation of the inertial navigation platform simulator and the swing table controller. The invention builds a semi-physical simulation experiment system under laboratory conditions, which can quickly verify the convergence of the collimation model to be tested.

Description

technical field [0001] The invention relates to the field of submarine-launched missile launching technology experiments, in particular to a method and a system for testing the alignment model of a submarine-launched missile inertial navigation platform. Background technique [0002] Submarine-launched missiles are called submarine-launched ballistic missiles, which refer to ballistic missiles launched by certain types of submarines. Before launching a submarine-launched missile, the inertial navigation platform of the missile needs to be initially aligned, that is, aiming at the position of the shooting target according to the collimation model, and then launch the missile. The alignment model needs to be tested before it can be used. The current test method is usually to build a reference azimuth transfer and platform alignment test system in the laboratory, and use physical simulation tests, that is, to build a reduced version of the missile inertial navigation platform ...
