Speed Over the Ground - The rate at which a vessel travels from point A to point B - can be affected by current, tide, and wind. eg: While walking quickly the wrong way up an escalator, you get nowhere fast. Your Foot Speed is faster than your SUS (Speed Up the Steps). Similarly, w hile sailing at 7 knots into a 4 knot opposing current, your Boat Speed would be 7 knots, while your Speed Over the Ground (SOG) would be only 3 knots. ( See also Boat Speed)
SPEED OVER GROUND. The speed of the vessel relative to the bottom, as opposed to the vessel's speed through the water. The speed over ground includes the negative or positive effects of the currents in the water.
Speed Over Ground. Digital reading that indicates your current ground speed. (Selectable in miles-per-hour, knots, or kilometers-per-hour)
Speed Over Ground. the speed at which the GPS unit and the person operating it are moving with respect to the earth's surface.
Speed Over Ground. The actual speed the GPS unit is moving over the ground. This may differ from airspeed or nautical speed due to such things as sea conditions or head winds. For example a plane that is going 120 knots into a 10 knot head wind may have a SOG of 110 knots.
peed ver the round The actual speed the vessel is moving over the bottom, rather than through the water.
Speed Over Ground. Marine term to tell you to ignore tidal and current effects.
Speed Over Ground: The speed the G.P.S. receiver is traveling.
Speed Over Ground. The actual speed the GPS is travelling regardless of direction.
