🔍 Key Concepts

• GMDSS DSC Distress alert requirements for position information • How connected GPS and manually entered position are used by the radio • What happens if the GPS position is old or the manual position is not updated

💭 Think About

• If the GPS is connected, does that absolutely guarantee the position is always correct? Think about signal loss or outdated data. • Is a connected GPS the only way that position can be included in a distress alert, or can the operator provide it another way? • When you push the distress button, what are the two possible sources of position data that the radio might send?

✅ Before You Answer

• Verify whether GPS connection is mandatory for sending a valid distress alert position. • Check if position can be manually entered and updated on a DSC radio for distress purposes. • Confirm that GPS-derived data can be wrong or stale if not recently updated or if the connection is lost.
