Which of the following are examples of U.S. military satellite systems?

• A. Hubble
• B. MILSTAR, AEHF, WGS
• C. Galileo
• D. GPS

Answer: (B)

The main idea is recognizing satellites that are dedicated to U.S. military communications. MILSTAR provides protected, jam-resistant strategic communications for national command and control. AEHF is its advanced successor, delivering higher data rates, global reach, and improved anti-jamming for survivable military links. Wideband Global SATCOM offers flexible, high-capacity, long-haul communications for a broad range of military users and works with legacy systems. Hubble is a NASA space telescope, Galileo is Europe’s GNSS, and GPS, while a U.S. navigation system with military use, is not a dedicated military communications network like MILSTAR, AEHF, and WGS. Taken together, MILSTAR, AEHF, and WGS best illustrate U.S. military satellite systems.
