The intended horizontal direction of travel. It is measured from 0° at the REFERENCE DIRECTION clockwise through 360°; strictly for MARINE NAVIGATION, the term applies to the direction to be steered, which sometimes differs from the direction intended to be made good over the GROUND (see DRIFT ANGLE). The course is designated as true, magnetic, compass, or grid as the REFERENCE DIRECTION is TRUE, MAGNETIC, COMPASS or GRID NORTH respectively. See COURSE MADE GOOD and TRACK. The channel in which water flows. See also WATERCOURSE.

1.所要行驶的水平方向。从参考方向顺时针从0°到360°量算。在航海中,该术语指实际驾驶方向,有别于航迹相对于地面的方向(参见drift angle(偏航角))。如果参考方向是真北、磁北、罗经北或坐标北方位,则航向也分别是真航向、磁航向、罗盘航向或坐标航向。参见course made good (航迹向)和track(航迹)。 2.水流通道。亦可参见watercourse(航道)。
course: compass
罗经航向
See COURSE.
参见course(航向)。
course: great circle

The direction of the GREAT CIRCLE through the point of departure and the destination, expressed as the ANGULAR DISTANCE from a REFERENCE DIRECTION, usually north, to the direction of the GREAT CIRCLE. The angle varies from point to point along the GREAT CIRCLE. At the point of departure it is called Initial Great-Circle Course; at the destination it is called Final Great-Circle Course.

所要行驶的水平方向,以基准方向为0°,顺时针由0°至360°量度。对于海上航行,严格地讲:航向系指实际行驶的方向,它有时与所要行驶的方向有差别。以真北、磁北、罗经北及坐标北为基准方向的航向分别称为真航向、磁航向、罗经航向和坐标航向。 亦指流水通道。亦可参见watercourse(航道)。
course line
航向线,航线
A LINE OF POSITION approximately parallel to the COURSE.
与航向大体平行的位置线。
course made good
航迹向

The actual TRACK MADE GOOD over the ground (seabed); the direction of the point of arrival from the point of departure. Course made good is the direction component of the resultant ship's velocity and the water current. Course made good should not be confused with HEADING, or ship's head.

相对于地面(海底)的实际航迹;从出发点到达终点的方向。航迹向是船舶速度和水流综合作用形成的方向,航迹向不应与船艏航向混淆。

The direction of the path over the ground actually followed by a vessel. It is normally a somewhat irregular line. This is a misnomer in that courses are directions steered or intended to be steered through the water with respect to a reference meridian. Also called track over ground.
