  • Space Surveillance refers to the series of activities that detect, track, estimate the orbit of, identify, and catalog asteroids, satellites, and space debris, including natural space objects.
  • The basic types of observation techniques for space objects are optical and radar observation.
  • Optical observation generates respective (angle) information. Radar observation generates information such as the distance (range), distance change (range rate), and angle with respect to the observer.
  • Currently, KASI has acquired the core technology necessary to develop space surveillance capabilities through the establishment of the OWL-Net optical space surveillance program. Research that will be used to build a radar surveillance system is ongoing.
  • Detection

    Activities to detect incoming satellites and space debris, projectiles, space objects within the observed range of the monitoring facilities

  • Tracking

    Activities to track the object within the initial orbit of ‘detection’

  • Identification

    Activities to identify the mission and nationality of the detected object with the precise orbit elements through ‘detection’ and ‘tracking’

  • Cataloging

    Activities to manage the database of collected data such as name, identification number, orbit elements, mission, etc.
