How might an installer verify correct GPS sentence to a marine DSC VHF radio?

• A. Check for the presence of error codes on the display.
• B. Look for latitude and longitude, plus speed on the VHF display.
• C. Reboot the system to refresh GPS connection.
• D. Use an external GPS device for comparison.

Answer: (B)

Verifying the correct GPS sentence to a marine DSC VHF radio is essential for ensuring that the radio can send accurate position information in distress scenarios. Checking for the presence of latitude and longitude, along with speed on the VHF display, directly confirms that the GPS data is being received and interpreted correctly. When the VHF radio displays accurate latitude and longitude coordinates, it indicates that the radio is receiving valid GPS sentences from the satellite system. The inclusion of speed can further validate that the GPS is functioning correctly, as it shows the movement status of the vessel. This information is crucial for marine communication, especially in emergencies, where precise location data must be transmitted. Other options like checking for error codes or rebooting the system may help in troubleshooting but do not directly verify active and correct GPS data being displayed or received. Similarly, using an external GPS device for comparison can provide additional information but is not as immediate or practical as simply checking the display on the VHF radio itself.
