Abstract Abstract： Aimed at the low convergence rate and unstable convergence performance of the generalized least squares algorithm on WGS84 coordinate, a modified generalized least square algorithm was proposed which took convergence steps as the weighting factor for measurement accuracy of the generalized least squares algorithm, making measurement accuracy vary with the changes of steps in order to achieve the decrease of the convergence steps and the advance of the stability after convergence. So this algorithm improves the performance of target tracking and positioning. Simulation results show that the modified generalized least square algorithm is superior to the generalized least square algorithm, verifying the feasibility of the proposed algorithm.
