Space Situational Awareness
Space Situational Awareness refers to understanding what objects are in space, where they are, what they're doing, and predicting their future positions to ensure safe and secure operations. It's essential for preventing collisions and monitoring potential threats in Earth's orbit.
TECHNICAL DEFINITION
Space Situational Awareness (SSA) is the comprehensive understanding of the space environment, encompassing the tracking, identification, and characterization of natural and artificial objects in orbit, along with predicting their future behavior. This multidisciplinary field utilizes ground-based and space-based sensors, data fusion, and advanced analytics to support safe space operations, mitigate orbital debris risks, and detect potential adversarial activities impacting national security and commercial assets.
BACKGROUND
The 18th Space Defense Squadron is a United States Space Force Space Domain Awareness unit located at Vandenberg Space Force Base, California. The 18th SDS is tasked with executing command and control of the space surveillance network (SSN), maintaining the resident space object (RSO) database and managing United States Space Command's space situational awareness (SSA) sharing program to United States, foreign government, commercial, and academic entities. The squadron also conducts advanced analysis, sensor optimization, conjunction assessment, human spaceflight support, reentry/break-up assessment, and launch analysis.
