Triple

Target class: laser ranging system
Context triple: [Laser Ranging Instrument, instanceOf, laser ranging system]

• A. lunar radar instrument
  A lunar radar instrument is a device designed to transmit radio waves toward the Moon and analyze their echoes to map surface and subsurface features, determine composition, and study lunar structure.
• B. ground-based radar system
  A ground-based radar system is a terrestrial installation that emits radio waves and analyzes their reflections to detect, track, and characterize objects or weather phenomena within its coverage area.
• C. satellite system
  A satellite system is an integrated network of orbiting spacecraft, ground stations, and communication links designed to perform functions such as communication, navigation, Earth observation, or scientific research.
• D. high-precision positioning technique chosen
  A high-precision positioning technique is a method or system that determines the exact location of an object or point with very fine spatial accuracy, often at the centimeter or millimeter level.
• E. radial velocity measurement method
  A radial velocity measurement method is a technique used to determine the component of an object's velocity along the line of sight, typically by analyzing Doppler shifts in its spectral lines.
• F. None of above.
