When comparing Inmarsat-B and Inmarsat-C terminals, which statement is accurate?

The accurate statement indicates that Inmarsat-B units are designed to provide greater communications capabilities compared to Inmarsat-C terminals. This is primarily due to Inmarsat-B's ability to support higher data rates and a broader range of services, including voice, fax, and higher bandwidth data transmission.

However, these enhanced capabilities come with certain trade-offs. Inmarsat-B terminals are generally larger and heavier, and they entail higher installation expenses and initial costs than Inmarsat-C terminals. The trade-offs are inherent in the advanced technology and functionality that Inmarsat-B offers, resulting in a more complex system that requires more substantial infrastructure.

In contrast, Inmarsat-C terminals prioritize simplicity and cost-effectiveness, making them lighter and less expensive to install. While they provide necessary communication capabilities, especially for basic data messaging and tracking, they do not match the overall functionality provided by Inmarsat-B terminals. Understanding these differences is essential for determining which system best suits specific communication needs.
