Which longitude corresponds to the POR satellite location for Inmarsat-B/C communications?

The Inmarsat-B/C satellite system operates from specific geostationary orbital positions to provide communication services, including maritime communications. For the Inmarsat satellites, they are positioned at certain longitudes above the equator, where they maintain a fixed position relative to the Earth.

The correct longitude for the Inmarsat-B/C satellite location is 178E. This orbital position allows the satellites to provide optimal coverage for maritime communication in various regions, including the Pacific Ocean and areas around the Americas and Asia. This positioning is critical because it ensures that vessels at sea can maintain reliable and continuous communication for safety and operational purposes.

The other options represent different longitudes that do not correspond to the known geostationary positions for Inmarsat-B/C satellites, making them incorrect choices in this context. Understanding the specific orbital positions of communication satellites is vital for ensuring the efficiency and reliability of maritime communication services.
