Question 68 Deck Safety

The correct answer is C) INMARSAT. INMARSAT, or the International Maritime Satellite Organization, is a satellite-based communication system that is least likely to be affected by atmospheric disturbances compared to the other options. INMARSAT uses geostationary satellites orbiting the Earth, which are not as susceptible to ionospheric interference or propagation issues caused by atmospheric conditions as the other systems that rely on terrestrial-based radio signals (HF NBDP, NAVTEX, and MF NBDP). The other options (A, B, and D) are more vulnerable to atmospheric disturbances, such as solar flares, ionospheric conditions, and weather patterns, which can degrade or disrupt the radio signals they rely on. INMARSAT's satellite-based system is more reliable and consistent in its performance, making it the least likely to be affected by atmospheric disturbances.
