Which stabilization uses course over ground and speed over ground?

Ground stabilization anchors the radar picture to the earth by using course over ground and speed over ground. By pulling COG and SOG from navigation sensors, the display compensates for the vessel’s actual movement over the ground (including drift from current and wind) so fixed features on shore remain in the same place on the screen. This makes plotting and tracking ground-based targets consistent, and it keeps bearings and ranges to fixed objects stable relative to the coast. In contrast, other stabilization modes tie the picture to the ship’s heading or to sea state, which would let shore features drift on the display as the ship moves.
