What does SST mean in UNCLASSIFIED

SST refers to the systematic collection and analysis of data to detect, track, catalog, and characterize satellites and other objects in Earth's orbit. It involves the use of various sensors, including radar, telescopes, and optical tracking systems, to monitor the movement and behavior of objects in space.

SST is crucial for several reasons:

• Avoiding Collisions: By tracking objects in space, SST helps prevent collisions between satellites and other spacecraft, which can lead to costly damage or loss.
• Space Traffic Management: SST provides situational awareness of the space environment, facilitating the coordination and management of satellite operations to prevent interference or congestion.
• Protection of Critical Infrastructure: SST helps identify and monitor potential threats to space-based assets, such as satellites used for communication, navigation, and defense.
• Scientific Research: SST data contributes to the understanding of the orbital environment, debris population, and space weather, supporting scientific research and exploration.

SST involves a multi-layered approach:

• Sensors: Ground-based radar, optical telescopes, and space-based sensors detect and track objects in orbit.
• Data Collection: Sensor data is collected and processed to generate position, velocity, and other characteristics of space objects.
• Cataloging: Object data is stored in databases and catalogs, which provide a comprehensive inventory of satellites and other space debris.
• Analysis: Experts analyze SST data to identify potential collision risks, track trends, and assess the orbital environment.

SST is primarily focused on surveillance and tracking of space objects, while Space Situational Awareness (SSA) encompasses a broader range of activities, including SST, as well as the assessment of potential threats, determination of collision risks, and dissemination of alerts.
