🔍 Key Concepts

• INMARSAT-C is primarily a data (text) and store-and-forward satellite service, not a voice service • Difference between store-and-forward messaging and real-time telex/voice communication • What kind of GMDSS (Global Maritime Distress and Safety System) traffic INMARSAT-C is designed to handle (distress alerts AND routine messaging)

💭 Think About

• Which option correctly identifies that messages are queued and delivered as data, rather than providing an open, continuous real-time circuit like voice or classic telex? • Does INMARSAT-C normally carry voice traffic at all, or is it limited to digital data and text messages? • Which description best matches both routine and distress communication capabilities, not just one or the other?

✅ Before You Answer

• Verify whether INMARSAT-C provides voice service (yes or no) • Verify whether INMARSAT-C is store-and-forward rather than a continuous real-time circuit • Check if describing the system only as providing "world-wide coverage" is specific enough to be the best technical description of how it works
