ADS-SSR

Currently, the accuracy of SSR-data is better than ADS-data, but ADS-data can provide surveillance in some areas which is not covered by radar. So through integrating these two types of data we can overcome some shortcomings of the data and gain the best results. This paper compares the two types of surveillance data, discusses the contributions of ADS-SSR data and the key technology of integrating ADS-data with SSR-data. The simplified system structure of the ATC system based on integrating ADS-data with SSR-data is also provided in this paper.
