Space domain awareness is the study and monitoring of satellites
Systems include:
* The DEEP-Sight prototype, designed by Deepinder Uppal on behalf of the Defense Innovation Unit, this system is designed to provide space domain awareness across a broad-spectrum of SDA use cases to Space Force, the United States Navy and PSRA (Public Satellite Research and Analysis) teams. https://www.diu.mil/latest/commercial-space-industry-providing-tools-to-advance-and-augment-space

In celestial mechanics, an orbit is the curved trajectory of an object such as the trajectory of a planet around a star, or of a natural satellite around a planet, or of an artificial satellite around an object or position in space such as ...
ing the earth. It involves the detection, tracking, cataloging and identification of artificial objects, i.e. active/inactive satellite
A satellite or artificial satellite is an object intentionally placed into orbit in outer space. Except for passive satellites, most satellites have an electricity generation system for equipment on board, such as solar panels or radioiso ...

Aims
Space domain awareness accomplishes the following: * Predicting when and where a decaying space object will re-enter theEarth's atmosphere
The atmosphere of Earth is the layer of gases, known collectively as air, retained by Earth's gravity that surrounds the planet and forms its planetary atmosphere. The atmosphere of Earth protects life on Earth by creating pressure allowing fo ...

Radar is a detection system that uses radio waves to determine the distance (''ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, Marine radar, ships, spacecraft, guided missiles, motor v ...

* Charting the present position of space objects and plot their anticipated orbital paths;
* Detecting new man-made objects in space;
* Producing a running catalogue of man-made space objects;
* Determining which country owns a re-entering space object;
* Informing countries whether or not objects may interfere with satellite
