🔍 Key Concepts

• Propagation characteristics of HF, MF, and VHF radio (skywave vs line-of-sight) • How satellite communications work compared to terrestrial radio • Which systems are most affected by ionospheric conditions, static, and fading

💭 Think About

• For each option, ask yourself: does this system depend on the ionosphere or ground/skywave propagation? • Which frequency bands are generally more prone to static, atmospheric noise, and fading: HF/MF or satellite-frequency links? • Is the signal path mostly line-of-sight through space, or does it travel long distances through the lower atmosphere and ionosphere?

✅ Before You Answer

• Identify which choices use HF/MF radio and are therefore subject to ionospheric fading and atmospheric noise • Identify which choice relies on a satellite link rather than direct HF/MF/VHF propagation • Confirm which system is specifically designed to provide very reliable, low-interference connectivity for GMDSS (Global Maritime Distress and Safety System)
