Abstract�� A method based on the least square estimation for movie transit rendezvous survey is proposed. In conventional direct algorithm. It is not easy to control the switching time of two equation. This new method is an iterative algorithm, it can obtain the moving object' spatial location at anytime used the redundant data of three transit and avoid the question of two equation'switch. Theoretical analyses and numeric simulations in the new choice of stations have shown that this method possesses the advantages in computation and the fast convergence rate.Compare with the conventional direct method.It can improves the measure precision of radar etc.
