| Abstract: | In this paper, the definition of navigation system integrity is introduced. The methods of celestial navigation are described. It is proposed that the celestial constellation could be applied in the satellite to satellite link positioning and autonomous integrity monitor for navigational constellation. The reasonable integrity check threshold is discussed. Moreover, the application of Kalman filter in feedback model is studied. Some meaningful conclusions are obtained from the study. |
