Which satellite types are used in Navy communications?

• A. LEO, MEO, GEO, Molniya Orbit HEO
• B. Only GEO
• C. Only LEO
• D. Only MEO

Answer: (A)

The main idea is that military satellite communications rely on a mix of orbital regimes to meet different mission needs. Each orbit type offers unique advantages, so Navy networks use them all to stay connected worldwide. LEO and MEO satellites provide lower latency and faster link setup, which is important for tactical, ship-to-ship, and near-real-time communications. GEO satellites give a large, stable coverage footprint with relatively predictable links, useful for global command and long-haul communications with fewer stations. For high-latitude operations, a Molniya-type orbits (highly elliptical with long dwell times over the poles) keep a satellite visible for extended periods when GEO coverage is weak at extreme latitudes. Highly Elliptical Orbits in general can be tailored to provide extended communication windows over specific areas or times, offering persistent coverage where needed. By combining these options, Navy planners can ensure global reach, reliable links in polar regions, acceptable latency for critical commands, and redundancy. That broad mix is why all the listed orbit types are used in Navy communications.
