Influence of Longitudinal Acceleration Parameters on the Ability of Instrument Error Estimation of Inertial Navigation System

摘要

The factors are investigated that allow you to improve the ability of error estimation for the strapdown inertial navigation system inertial sensors—gyroscopes and accelerometers—during the flight of the aircraft. The main tool that solves this problem is the trajectory conditions that ensure the alternation of longitudinal acceleration. Several scenarios of aircraft movement with variable longitudinal acceleration are considered. The results of simulation of inertial sensor error estimation are presented.
