It is a difficult to determine the position in fast GPS positioning because of containing the outliers in observation data and the lack of enough observation information to make the design array be in partial ill-condition.A new robust biased estimator-robust partial ordinary ridge estimator (RPORE) is proposed. The selection method for choosing the partial ridge parameter is established. The computed results of GPS data show that the new estimator has the characteristics of high precision,fast speed and stability.
