detects and updates the vessel position and the local time.

the vessel position and the local time manually, using the GPS/DATA option.
This information is important because it will be used if a DSC distress call is transmitted.
You can also enter the course (COG) and speed (SOG) and select GPS Alert and GPS Simulator options.
