launch less-capable satellites routinely on rideshares to characterize deep space highinterest<br />

objects and drifting satellites nearing end of their life in geosynchronous orbit. 2)<br />

To enable responsiveness, acquire more sensors and dedicated assets to enable focusing<br />

attention on high-interest objects and ensuring robust coverage of high-interest areas,<br />

enabling our ability to respond to multiple events. 3) Increase the number of sensors,<br />

creating a layered SSA approach, which brings all contributing space systems and sensors<br />

onto a single network to enable data sharing and timely information dissemination. 4)<br />

Invest in artificial cognition to automate many SSA functions to respond to the increasing<br />

complexity and to operate at the speeds required by 2020.<br />

Persistent Space Situational Awareness: Distributed Real-Time Awareness Global<br />

Network in Space (DRAGNETS)<br />

Dustin “Zig” Ziegler, Major, USAF<br />

U.S. dependence on space brings with it an inherent vulnerability and a<br />

compelling need for robust Space Situational Awareness (SSA). Over the next 20 years,<br />

nanotechnologies will enable a shift toward distributed networks of very small satellites<br />

to maintain continual cognizance of the space environment. The Distributed Real-time<br />

Awareness Global Network in Space (DRAGNETS) concept leverages this trend using<br />

constellations of thousands of sugar cube-sized “femtosats” instead of the current<br />

paradigm of large, specialized, one- or few-of-a-kind systems. The recent explosions in<br />

nanotechnology research and projections for even greater future growth have laid the<br />

foundation for the substantial miniaturization that will be required. Advances in sensors,<br />

propulsion, processing, power, and other key satellite subsystems will enable the Air<br />

Force to package SSA capabilities on the femtosats, allowing DRAGNETS to perform<br />

the mission globally on a continuous basis.
