Abstract

The navigation performance of Global Navigation Satellite System was affected by distortional signal. According to the ICAO research on navigation signal anomaly, the mathematical model for BeiDou's digital and analog mixed distortion was established. Then, the correlation domain and frequency domain were analyzed. Finally, in accordance with S-curve locking point bias of TMC, the impact on measurement performance was deeply analyzed. The simulation results demonstrate that the correlation peak and power spectrum were deformation, the navigation performance of BeiDou was reduced, and the integrity for augmentation system was influenced.

Key words： threat model of TMC; correlation correlation function; power spectrum; correlation loss; S-curve
