The closer the interference station is deployed to the area near the transmitting station, the more obvious the interference effect will be. However, due to the power characteristics of the satellite transparent transponder, its position change in the ne

The results show that the single satellite integrity risk of the system in the quarter caused by the event is 2.23?×?(10.), and the continuity risk of PRN21 satellite is 0.398%, both of which are far higher than t
