Abstract

The invention belongs to the technical field of inertial navigation and relates to a ground-based simulation test method for the automatic navigation function of an inertial navigation system. The ground-based simulation test method is free of the involvement of a flight control system and has low requirements for a turntable; a dual-axis hand-operated turntable is employed in stead of a three-axis hydraulic automatic turntable, and mutual cross-linking is reduced; besides, instruments such as an angular rate gyroscope and the like are reduced; the section of air routes covers all possible flight modes; people and devices joining in the test are few, so that the test is easy to organize and implement; the test is short in period and low in cost; and the method is simple and practicable.

Description

technical field [0001] The invention belongs to the technical field of inertial navigation, and relates to a ground simulation test method for an automatic navigation function of an inertial navigation system. Background technique [0002] At present, the automatic navigation test is a closed-loop feedback control system composed of inertial navigation system, flight control system, three-axis hydraulic simulation turntable, HMJ-200 analog computer and angular velocity gyroscope, such as Image 6 shown. [0003] Among them, the HMJ-200 analog computer simulates the lateral motion of the aircraft, calculates the roll, heading and angular velocity of the aircraft according to the equation of motion of the aircraft, controls the roll and heading loops of the simulated turntable, and reproduces the lateral motion of the aircraft. The meter sends a lateral acceleration signal to the flight control system. [0004] The inertial navigation system measures the roll and heading of t...
