H_∞ filter applied in GPS dynamic locating
YU Yun-zhi · Electronics Optics & Control · 2007
The error of model usually increases dramatically in GPS dynamic locating,thus a H∞ filter based GPS dynamic locating method is put forward.Due to the robustness of H∞filter,the proposed method is able to decrease the current acceleration model error.The example showed that the method performs well in GPS dynamic locating.Compared with the normal Kalman filter based on the current acceleration model,what makes the method distinctive is that it is easy to implement with reduced calculation cost and increased filter accuracy.
