Correction and Prediction of Aircraft Single-station Burst Positioning Data
Wei Min Qi · Radio Engineering · 2011
Discontinuous and illegal data exists in single-station positioning results due to wireless channel characteristics,aircraft attitude,multipath and noises.In consideration of the features of data burst and jump points,break points and spikes existing in positioning data,a data correction technique based on 3б criteria and Kalman filtering policy is proposed.This technique can effectively minimize jump points,reconstruct break points,smooth spikes,and improve the continuity,effectiveness and reliability of positioning data.The principle of single-station burst positioning is introduced.The 3б criteria and Kalman filtering correction algorithm are explained.Flight test validation shows that this method is feasible and effective for data correction and prediction in single-station burst positioning.
