Triple

Target class: cooperative surveillance system
Context triple: [ADS-B, instanceOf, cooperative surveillance system]

• A. infrared surveillance system
  An infrared surveillance system is a security solution that uses infrared sensors and cameras to detect, monitor, and record heat signatures in low-light or no-light environments for continuous observation and threat detection.
• B. cooperative security activity
  A cooperative security activity is a coordinated effort among multiple actors—such as states, organizations, or agencies—to jointly prevent, mitigate, or respond to security threats through shared information, resources, and actions.
• C. multispectral targeting system
  A multispectral targeting system is an integrated sensor and processing suite that detects, tracks, and designates targets across multiple parts of the electromagnetic spectrum (e.g., visible, infrared, and radar) to enhance accuracy and situational awareness.
• D. satellite surveillance base
  A satellite surveillance base is a secure ground facility equipped with advanced antennas, control systems, and data-processing infrastructure used to monitor, receive, analyze, and manage information from surveillance satellites orbiting the Earth.
• E. space surveillance sensor
  A space surveillance sensor is a device or system that detects, tracks, and characterizes objects in space to support situational awareness, collision avoidance, and space traffic management.
• F. None of above. chosen
