Question 1 of 27070

Which mode of communications is NOT possible through an Inmarsat-C SES?

🔍 Key Concepts

• Inmarsat-C capabilities as a narrowband, store-and-forward digital service (no real-time audio/voice) • Difference between data / TELEX messaging and analog services like voice or fax • How distress / emergency alerting is handled by an Inmarsat-C ship earth station (SES)

💭 Think About

• List which services Inmarsat-C is specifically designed to handle (think: text and data vs. real-time media). Which of the options clearly needs a real-time, continuous connection? • Consider how GMDSS uses Inmarsat-C for distress alerts. Which option matches that function most closely? • Among the four choices, which one would normally require transmission of a continuous image signal rather than short text or data packets?

✅ Before You Answer

• Verify which options are store-and-forward digital text/data types (Inmarsat-C strength). • Verify whether Inmarsat-C supports fax or facsimile directly, or if that is usually done over other Inmarsat systems (like A/B/M/F). • Confirm that distress / emergency activation is a defined feature of Inmarsat-C under GMDSS.
