The EUROCONTROL Surveillance Data Distribution System (SDDS) is a versatile, high-performance communications gateway that provides value-added services for the safe and secure distribution of ASTERIX (EUROCONTROL’s All purpose Structured suRveillance Information eXchange) format.
SDDS enables ANSPs to exchange surveillance data, in an efficient manner, contributing to the reliable and efficient operation of the pan-European ATM network.
With the objective to protect ATC system from deficient data from upstream systems that may harm it, SDDS:
- checks surveillance data for syntactic and semantic errors (deep packet filtering);
- provides firewall services;
- is able to filter out data that may cause processing problems;
