🔍 Key Concepts
• Inmarsat FleetBroadband system architecture – how the above-deck antenna unit and below-deck unit are split
• Typical components of a stabilized maritime satcom antenna (what must physically be near the radome vs. in the rack below decks)
• Role of an Antenna Control Unit (ACU) and separate GPS antenna in tracking the satellite
💭 Think About
• Which options list components that would logically be located together inside or directly attached to a small shipboard radome for FleetBroadband (L‑band), rather than inside a below‑deck rack?
• Do FleetBroadband terminals normally need a high‑voltage/large AC power module in the radome itself, or is power conversion usually done below decks?
• Between a parabolic dish, phased array, and stabilized antenna description, which best matches the compact, self‑contained L‑band terminals used for FleetBroadband?
✅ Before You Answer
• Check which items are typically inside the radome (stabilized antenna, RF electronics, ACU functions) versus below decks (main control unit, high‑power supplies).
• Verify whether FleetBroadband uses large parabolic dishes or phased arrays, or a small, self‑tracking stabilized antenna unit.
• Confirm that GPS for satellite terminals is often provided by a separate GPS antenna, not necessarily integrated into a big parabolic dish assembly.
