Space Domain Awareness
Space Domain Awareness (SDA) is the ability to know what objects are in orbit, where they are, and what they are doing. This includes natural phenomena like space weather, as well as artificial satellites and debris.
TECHNICAL DEFINITION
Space Domain Awareness (SDA) is a critical intelligence function encompassing the tracking, identification, and characterization of all natural and artificial objects in Earth's orbital environment to understand their status, intent, and potential threats to space-based assets or terrestrial operations. It leverages a global network of multi-modal sensors (e.g., radar, optical, radio frequency) and advanced data analytics to maintain a comprehensive, real-time catalog of space objects and predict their behavior.
BACKGROUND
The United States Space Force (USSF) is the space service branch of the United States Armed Forces, and was established on 20 December 2019. Part of the United States Department of Defense, it is one of the six armed forces and one of the eight uniformed services of the United States. It is the second independent space force to have been formed, after the Russian Space Forces; together with that of China, it is one of only two still extant.

USAGE NOTE
SDA is vital for ensuring the safety of space operations, protecting critical satellite infrastructure, and informing strategic military decisions in the increasingly congested and contested space domain.
DEVELOPERS
Organizations developing technology related to Space Domain Awareness.
The US Space Force is the primary service branch of the United States Armed Forces responsible for organizing, training, and equipping space forces, and for conducting operations in and through space. A core mission is Space Domain Awareness (SDA), ensuring the US and its allies maintain freedom of action in space by understanding the space environment.
A global aerospace and defense technology company that develops and provides advanced space systems, sensors, and ground infrastructure for Space Domain Awareness, including satellite tracking, identification, and characterization.
A major defense contractor that designs, develops, and integrates a wide range of space technologies and systems for national security, including ground-based and space-based sensors, data fusion, and command and control systems crucial for Space Domain Awareness.
