Accuracy Analysis and Ionospheric Compensation of Radio Navigation and Positioning System under Dynamic Sea Surface Background

Abstract

This paper first analyzes the ionosphere loss model is established based on analytic method, a nonlinear sea spectrum as the theoretical foundation of ship swaying in the waves of the sea model is set up, and then the numerical method is adopted to establish the waves with the wind blowing the typical three-dimensional model, and converted into a mathematical model of ship longitudinal and transverse swing and using high frequency approximation method to calculate the surface of radio navigation signal amplitude and phase of contribution, finally through the simulation data post-processing and statistical analysis, got the Marine radio navigation signals compensation strategy and specific methods.
