Which domain concerns navigation, satellite communications, and surveillance?

• A. Air
• B. Space
• C. Land
• D. Maritime

Answer: (B)

Navigation, satellite communications, and surveillance rely on orbital assets and space-based infrastructure, which places them in the space domain. Navigation uses satellites to provide precise location and timing data, satellite communications depend on space relay satellites to connect distant points, and surveillance is conducted from space through reconnaissance satellites that gather imagery and other intelligence. The other domains cover different environments—air with aircraft, land with ground forces, and maritime with ships and oceans—so space is the best fit for these capabilities.
