Which system provides maximum communications range?
AI Explanation
The correct answer is B) INMARSAT.
INMARSAT, or the International Maritime Satellite Organization, provides global satellite-based communications coverage, which allows for the maximum communications range compared to the other options. INMARSAT systems can establish communications at much greater distances from shore, often thousands of miles, making it the most suitable choice for long-range maritime communications.
The other options, such as Digital Selective Calling (DSC) on 8414.5 kHz, VHF ARQ, and MF SITOR, are more limited in their communications range, as they rely on traditional radio frequencies that have a reduced range compared to satellite-based systems like INMARSAT.
