Helios optical reconnaissance system

Target entity: Helios optical reconnaissance system
Context triple: [CSO, successorTo, Helios optical reconnaissance system]

• A. Space-Based Infrared System
  The Space-Based Infrared System (SBIRS) is a U.S. military satellite constellation designed to provide global missile launch detection, missile defense support, and strategic infrared surveillance.
• B. KH-10 DORIAN reconnaissance camera system
  The KH-10 DORIAN reconnaissance camera system was a highly advanced, large-format optical imaging payload developed during the Cold War for the U.S. Manned Orbiting Laboratory to capture extremely high-resolution photographs of Earth for intelligence purposes.
• C. Yaogan reconnaissance satellites
  Yaogan reconnaissance satellites are a series of Chinese military and intelligence-gathering spacecraft used for activities such as optical imaging, radar surveillance, and electronic intelligence collection in orbit.
• D. Erieye radar
  The Erieye radar is a Swedish airborne early warning and control (AEW&C) radar system known for its active electronically scanned array (AESA) technology and long-range surveillance capabilities.
• E. NATO Alliance Ground Surveillance
  NATO Alliance Ground Surveillance is a NATO-operated intelligence, surveillance, and reconnaissance program that uses high-altitude unmanned aircraft to provide member nations with persistent, wide-area ground and maritime situational awareness.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
