SDA
Space Domain Awareness (SDA) is the comprehensive understanding of everything happening in space, including the location and activity of satellites, space debris, and potential threats. It's essential for safe and secure operations in the space environment.
TECHNICAL DEFINITION
Space Domain Awareness (SDA) is the foundational intelligence capability involving the detection, tracking, identification, characterization, and attribution of all objects, activities, and events within the space domain, providing actionable insights for national security, assured space operations, and strategic decision-making regarding space assets and potential threats.
BACKGROUND
The Space Development Agency (SDA) is a United States Space Force direct-reporting unit tasked with deploying disruptive space technology. One of the technologies being worked on is space-based missile tracking using large global satellite constellations made up of industry-procured low-cost satellites. The SDA has been managed by the United States Space Force since October 2022. By February 2024 the SDA had 38 satellites on orbit. SDA intends to have at least 1,000 satellites in low Earth orbit by 2026.
