N2 - Based on BeiDou-2 constellation navigation, properties of a relatively new method, unscented Kalman filter and the most classical method, batch least squares method are discussed. First, the research progresses of these two estimation methods are summarized, and then the principles of unscented Kalman filter and batch least squares method are briefly reviewed. Sensitivity analysis of orbit determination results to different measurement errors, measurement data-sampling periods, and dynamic model errors, are made with classical unscented Kalman filter and batch least squares method. By comparison n, conclusions are drawn about choice of estimation method in constellation navigation.
