When we are at sea we  our position  gets automatically uploaded to Google earth follow the link

We have set it to update every 12hours, using the “Yellowbrick” Iridium tracking system.If we are in a city /port for more then a few days, then this system is usually put on standby  for the duration of our port visit.

The frequency of the position updates can be adjusted to the charterers requirements.
