# AIS-subscription

You can enable or disable the subscription to AIS-positions for a vessel. There is an icon on the top right corner of a vessel drawer. If the icon is light grey it indicates that the vessel has no IMO-number registered. If the icon is darker grey it indicates that it is not subscribing to AIS-positions. If the icon is blue it indicates that the vessel is subscribing to AIS-positions.
