Space domain awareness

From Wikipedia, the free encyclopedia
(Redirected from Space Situational Awareness)

Space domain awareness is the study and monitoring of satellites orbiting the Earth. It involves the detection, tracking, cataloging and identification of artificial objects, i.e. active/inactive satellites, spent rocket bodies, or fragmentation debris.

Aims

[edit]

Space domain awareness accomplishes the following:

  • Predicting when and where a decaying space object will re-enter the Earth's atmosphere;
  • Preventing a returning space object, which to radar looks like a missile, from triggering a false alarm in missile-attack warning sensors;[1]
  • Charting the present position of space objects and plot their anticipated orbital paths;
  • Detecting new human-made objects in space;
  • Producing a running catalogue of human-made space objects;
  • Determining which country owns a re-entering space object;[1]
  • Informing countries whether or not objects may interfere with satellites and International Space Station orbits;
  • Providing data for future anti-satellite weapons systems.

Systems

[edit]
Ground-based electro-optical deep-space surveillance telescopes at White Sands Missile Range.

Systems include:

Silentium Defence Oculus Observatory
