Abstract

Airborne inertial navigation system alignment on ground stationary base requires a long alignment time

which seriously affects departure speed of aircraft.In order to assist the airborne inertial navigation system to align quickly and accurately

a laser ranging device is designed to acquire the heading information by measuring the landmarks on the aircraft.Firstly

the structure and basic principle of the measuring device are described.Then the measurement formula of aircraft heading angle using this device is deduced

and the complete process of calibration and measurement is given.Finally

the ranging error

pitch error and azimuth angle error of the measuring instrument are analyzed by simulation experiment.
