| Abstract: | The key technology of real-time assessment of actual navigation performance(ANP) required in performance based navigation(PBN)is dealt with PBN implementation,can help to reduce separation between the routes and thus increase airspace usages with high reliability.ANP calculation of onboard hybridized navigation systems is presented.The standard error of position is extracted by partitioning the covariance matrix of Kalman filter.The error ellipse is changed into 95 % confidence error circle using the standa... |
