| Abstract: | To get the position of target by TDOA in three satellites constellation TDOA location system is a nonlinear location problem. The method using the position points has some limitations. An algorithm which can adapt incomplete data is presented. Better performance in this case is indicated by simulation results, and engineering problem is solved in effect. |
