Satellite Communication and Navigation

课程简介

/ Indicative Syllabus Introduction of Guidance, Navigation, and Control – the role of GNC in autonomous systems, the relationship between navigation, and guidance and control, positioning to navigation. Introduction of GNSS – system architecture, global coordinate systems, time reference and GPS time system, radio frequency spectrum of GNSS signal, future plan of GNSS. Receiver signal processing – Digtal signal processing, GPS signal acquisition, GPS Signal tracking, delay lock loop and phase lock loop, decode GPS navigation data. Position, velocity and timing estimation – pseudo range, linear estimation for GPS position, weighted least square, dilution of precision, velocity estimation, carrier smoothing. GNSS measurement and error source – control segment error, signal propagation modeling errors, measurement error, user range error URE. Improved GNSS navigation – differential GNSS, real-time kinematics RTK, GPS/INS integration, Kalman filter, multipath mitigation. GNSS navigation in civil aviation use – accuracy and integrity, receiver autonomous integrity monitoring RAIM, satellite based augmentation system -- 1 of 3 -- SBAS, ground based augmentation system GBAS. Challenges and threats of GNSS receiver – Radio frequency interference spoofing, none-light-of-sight (NLOS) reception
