WebFeb 27, 2024 · Speed through water or speed over ground. This is one of the most common doubt seafarers have about Doppler log. The Doppler log measures the speed with respect to the surface reflecting the transmitted wave. In deep water the transmitted wave gets reflected by water layer which gets denser as the depth increases. WebDec 8, 2024 · Roll is how we describe the tilting motion of the ship from side to side. Wind and waves push against the ship and cause it to rock back and forth. Yaw spins the ship on an invisible middle line similar to swiveling on a chair. This can be caused by waves moving in perpendicular to the motion of the ship and can change its heading, or direction. how to set up homegroup https://bioforcene.com
