Here are some abbreviations that might help to understand what is going on.
Lat - Latitude is the co-ordinates that go up and down the global.
Long - Longitude is the co-ordinates that go around the world.
SOG - Speed Over Ground, this is the speed of the vessel over the sea bed.
COG - Course Over Ground, this is the course the vessel is heading in over the sea bed.
Heading - is the course the vessel is literally heading in, because breeze and currants effect the COG and Heading so these can be quite different.
D.T.G - Distance to Go
E.T.A - Expected time of arrival
N.M - Nautical Mile, is exactly 1,852 metres
