Effect of Yaw Angle Error in an Aircraft's Aerial Triangulation

摘要

Yaw angle Error was excluded in normal ground Triangulation. But in aerial triangulation, Yaw angle error of Direction-Finding (DF) platform is one of important factors which affect location precision. The theoretical GDOP of aerial triangulation is introduced out which included the yaw angle error of DF platform, the general GDOP distributions of aerial triangulation was brought out by simulation. The results showed that yaw angle error of DF platform degenerate location precision of aerial triangulation.
