چکیده انگلیسی:
The space-based Automatic Dependent Surveillance - Broadcast (ADS-B) is a new technology for air traffic
management. The satellite equipped with spaceborne ADS-B system receives the broadcast signals from aircraft
and transfers the message to ground stations, so as to extend the coverage area of terrestrial-based ADS-B. In this
work, a novel satellite single-axis attitude determination solution based on the ADS-B receiving system is pro
posed. This solution utilizes the signal-to-noise ratio (SNR) measurement of the broadcast signals from aircraft to
determine the boresight orientation of the ADS-B receiving antenna fixed on the satellite. The basic principle of
this solution is described. The feasibility study of this new attitude determination solution is implemented,
including the link budget and the access analysis. On this basis, the nonlinear least squares estimation based on
the Levenberg-Marquardt method is applied to estimate the single-axis orientation. A full digital simulation has
been carried out to verify the effectiveness and performance of this solution. Finally, the corresponding results are
processed and presented minutely.
