Analysis of large scale ionospheric tilts effects on the error of single site location

This paper analyzes the effect of large scale ionospheric tilts on the errors of single site location by establishing a simplified model for large scale ionospheric tilts in a three-dimensional coordinate. An equation including the coordinate of the reflection point and a numerical resolution to the equation based on Newton-Raphson iterative algorithm are given. Then the curves of error of single site location versus tilts angle, direction and target range is given by simulations.
