2024年7月31日 · SOG is the speed of a boat relative to the Earth’s surface, taking into account external factors like wind, currents, and tides. COG is the actual path traveled by a vessel from one point to another, while COG is the course that a GPS displays (a GPS without a compass connected to it).

2024年10月20日 · SOG (Speed Over Ground) 定义：SOG 表示地面速度，指的是船舶相对于地面的实际速度，而非相对于水的速度。SOG 反映了船只的实际前进速度，考虑到了水流、风等因素的影响。 用途：SOG 对于估计到达时间、计算航行距离等都是必需的信息。在海图界面上，SOG …

2025年2月12日 · The key takeaway is this: STW and SOG are complementary, not competing, metrics. STW is about safety. It gives you a real-time understanding of your vessel’s movement through the water, which is essential for collision avoidance and open-water navigation. SOG is about efficiency and precision.

The SOG patches became popular after the war, and I found some at an Army Surplus store in the late 80's. The first time I saw the SOG emblem used in a Hollywood movie was on a tee-shirt worn by a young teenage wannabe-vampire-killer in the comic teen scream movie, The Lost Boys.

In this paper, a solution to the problem of following a curved path for underactuated unmanned surface vehicles (USVs) with unknown sideslip angle and model uncertainties is studied. A novel...

2007年10月4日 · SOG is a resultant of speed through the water, current and leeway. In a simple example, if your vessel is making 10 knots into the face of a 3-knot current, your SOG will be 7 knots. Similarly, COG is not necessarily the same as true or magnetic heading.

Existing vessel travel time prediction models primarily rely on path-finding algorithms and corresponding distance/speed relationships to calculate travel time.

2019年9月30日 · 本文介绍了两种基本的白平衡算法：Gray World和White Patch，以及一个更一般的算法SoG（Shades of Gray）。 Gray World假设图像的平均颜色是无色的，White Patch假设图像中存在白色像素点。

2023年7月7日 · Speed over ground (SOG) is a critical aspect of aviation that pilots must consider throughout their flights. By accurately calculating and monitoring SOG, pilots can optimize flight planning and navigation, maintain safe airspeed, and ensure safety during crosswind operations.
