Satellites that provide communication, GPS, and intelligence support are space-based assets; their operation and reliability depend on the space environment and space infrastructure. Because these core capabilities originate in and are sustained from space, the space domain becomes the most critical for this mission—the assets themselves live and operate there, delivering the links, timing, and ISR data that all other activities rely on. Without space-based assets, satellite communications would fail, GPS timing and positioning would be lost, and intelligence support from satellite sensors would vanish, crippling coordination and situational awareness. Air, land, and sea rely on the data and connectivity space enables, but the fundamental source of those capabilities is the space domain itself.
