Which systems are inputs for FUSION in surveillance?

The correct choice identifies the systems that are integral inputs for FUSION in surveillance. In the context of aviation surveillance, FUSION refers to the process of integrating data from various sources to create a comprehensive situational awareness picture.

RSE (Radar Sensor Equipment) and ADS-B (Automatic Dependent Surveillance-Broadcast) are two critical systems that provide essential positional data. RSE offers primary radar information, while ADS-B enhances that data by broadcasting an aircraft's GPS position periodically. SMGCS (Surface Movement Guidance and Control System) contributes to surface traffic management, ensuring that ground movements are well-coordinated. MLAT (Multilateration) uses time difference of arrival of signals from transponders to determine aircraft positions accurately.

Together, these systems provide a multifaceted view of both airborne and ground traffic, allowing air traffic controllers to monitor and manage flight operations safely and efficiently. This comprehensive input is necessary for effective FUSION, as it collates various data sources for better analysis and situational awareness.

Other options do include systems that are relevant in aviation; however, they do not encapsulate the well-rounded input necessary for FUSION in surveillance. For instance, ATIS (Automatic Terminal Information Service) and CVIDS (Closed
