Abstract The United States operates a diverse set of more than two dozen radar and optical facilities around the world to monitor near-Earth space. The mission of the Space Surveillance Network (SSN) to detect, track, catalog, and identify all man-made objects in space pertains not only to routine space operations but also to special event processing, e.g., satellite breakups. The SSN provides both the Government and the civilian space communities with a wide variety of services and products, including comprehensive historical records on more than 22,000 objects and current, high fidelity orbital parameters on approximately 7,000 satellites now in Earth orbit. Although upgrades to both sensors and processing techniques continue to increase the sensitivity and capacity of the SSN, modifications to the operational procedures at existing facilities and the employment of special, non-network sensors can provide additional insight concerning the magnitude of the Earth satellite population which lies below the normal network reporting level.
