## What project 673940 buys

Space Domain Awareness (SDA) is one of four U.S. Space Force Enterprise Functions and is defined as the ability to detect, characterize, attribute, predict, and target activities in the space domain to inform decision making. SDA is comprised of the following Enterprise Activities: Reconnaissance, Surveillance, Conjunction Assessment, Collision on Launch Assessment, Breakups, and Rendezvous and Proximity Operations Support. As the foundation for space control, SDA encompasses surveillance of all space objects and activities; detailed surveillance of specific space assets; monitoring space environmental conditions; monitoring cooperative space assets; gathering indications and warning on adversary space operations; and conducting integrated command and control (C2), communications, processing, analysis, dissemination, and archiving activities. Space Situation Awareness Operations (SSAO, 1203940SF) fields, upgrades, operationalizes, operates, and maintains Space Force sensors and information/data integration capabilities within the SDA network while companion program element Space Situational Awareness Systems (SSAS, 1206425SF) develops new network sensors and associated information integration capabilities across the network. Activities funded in this program (1203940SF) focus on surveillance of objects in earth orbit and beyond to aid tasks including satellite tracking; space object identification; tracking and cataloging; satellite attack warning; notification of satellite flyovers to U.S. forces; space treaty monitoring; and technical intelligence gathering. As a whole, this program upgrades, modifies, modernizes, operationalizes, fields, operates, and maintains sensors and information integration capabilities for an integrated, end-to-end SDA architecture that provides critical national security space solutions on tactical operational timelines. The Space Data Fusion (SDF) effort (673940) includes the Global Sensor Watch (GSW) program, which develops and/or upgrades SDA data collection and exploitation capabilities, including artificial intelligence/machine learning (AI/ML), as modernization and improvement efforts to operational SDA capability.

**R-3 lines of work:** Product Development; Management Services.

> Activities carry the prior, current and budget year only — no five-year plan. In the request year they partition this project exactly; in earlier years they can under-cover it.

### Global Sensor Watch (GSW)

Continue Global Sensor Watch (GSW) efforts including: -Expand development and deployment of MACHINA delivering operator-on-the-loop capability and user restrictions with commercial, allied, and DoW SDA capabilities for automated sensor orchestration and integration with operational C2 (Space C2, Integrated Sensor Support Services (IS3)…

Congressional marks, the R-2 mission description and acquisition strategy, the industry vs government split of the whole request, and related program elements are recorded at **program-element** grain — an NDAA mark lands on a PE, never on a project.
