| Abstract: | In 3D angle only target localization system, the model and algorithm are important to better estimate the performance. The own plane NED inertial reference, the own plane body reference, and the antenna reference are introduced to model the position estimation problem with airborne sensor. Then three state equalities and four filtering algorithms are compared by simulation for choosing the best one. |
