Numerical Simulation of Inertial Navigation Technology and Arbitrary Path Generator

Abstract

To test the hardware or software of a strap-down inertial navigation system, or conduct a related simulation study, the flight trajectory data and the output parameters of gyroscope and accelerometer should be known in advance. And in practice a set of discrete data is often used to represent flight trajectory information. Therefore this paper proposes a new method that can produce discrete trajectory of any path, so that we can quickly generate required simulation trajectories according to the actual task requirements. This paper also optimizes the inertial device simulation model, presents a co-simulation idea of the trajectory generator and inertial navigation system. And this paper gives the simulation results of the whole system. By analyzing the simulation results, we can verify the correctness and feasibility of the method described above and the overall design of the simulation system.
