Which system provides high-speed one-way information flow of high volume data in MILSATCOM wideband segment?

• A. Defense Satellite Communication System
• B. Navy Multi-Band Terminal
• C. Advanced Extremely High Frequency
• D. Global Broadcast System

Answer: (D)

The system described is built for high-speed, one-way dissemination of large data volumes across a wideband downlink. Global Broadcast System is designed for exactly that: a global, high-rate, one-way broadcast that delivers vast amounts of data to many receivers without requiring a return link. This makes it ideal for distributing imagery, maps, and other large data sets to users worldwide.

In contrast, the Defense Satellite Communications System provides two-way, interactive communications; the Advanced Extremely High Frequency system focuses on protected two-way links, and the Navy Multi-Band Terminal is a user terminal rather than a broad, one-way broadcast service.
