tion on GPS accuracy. When visible satellites are close together in the sky, the ge-
ometry is weak and the DOP value is high, When the satellites are far away from 
one another, the geometry is strong and the DOP value is low.

•  ALT is the height of your GPS antenna above the surface of the water.

•  The diagram at the left part of the screen shows the information shown below.
