Aiming at the intense non-linearity of the state and measurement equations which are established in geodetic coordinate system, a new algorithm based on unscented Kaman filter (UKF) was proposed. In Unscented Kalman filtering, the updating of the filtering based on the nonlinear system equation was realized by designing a few sigma points and calculating the propagation of these sigma points via non-linear functions.UKF has great convenience in computing,because it does not have to get the complicated Jacobian matrix which cannot be avoided in the ordinary extended Kalman filtering(EKF). The simulation results show that the algorithm is feasible and efficient
