Which system functions as a Space-Based Sensor specifically for Space Surveillance?

• A. SBSS
• B. GSSAP
• C. WGS
• D. DMSP

Answer: (A)

Space-based space surveillance is about having sensors in orbit that continuously observe and track objects in orbit to build and maintain the catalog of resident space objects. The system in question is designed specifically for this role, using an onboard telescope to capture images and derive tracks that feed the Space Surveillance Network, improving detection, identification, and orbital data across different orbital regimes.

While other options relate to space operations, they serve different primary missions. The Geosynchronous Space Situational Awareness Program focuses on close-in observations of GEO objects for reconnaissance, rather than maintaining the general object catalog. The WGS satellites provide communications, not surveillance. The DMSP satellites monitor weather. So the space-based sensor built explicitly for space surveillance, with the goal of tracking and cataloging objects, is the best fit.
