| Abstract: | In this paper, a self location method is proposed. Constrained by the coordinates of control points, the parameters of self location are solved by Levenberg Marquardt algorithm which is a nonlinear least square method. Taking the example of double transmitters, the solution model of the self location method is introduced in detail. By the experiment, it is verified that the self location method is feasible, the solution model is effective and the accuracy of self location can meet the requirements of engineering survey. |
