The MilSat Symposium serves as a bridge between national space defense and industry. As low cost space technology proliferates worldwide, DoD has more choices in the rapid development and deployment of next-generation space defense technologies. Space operations have a critical role in interconnecting the services and an increasing role in the defense of space assets. The MilSat Symposium fosters discussion on these new and developing connections while addressing the technological, logistical and financial understandings needed to build next-generation space defense.
