Course Angle

course angle

[′kȯrs ‚aŋ·gəl]
(navigation)
Course measured from 0° at the reference direction clockwise or counterclockwise through 90° or 180°; it is labeled with the reference direction as a prefix and the direction of measurement from the reference direction as a suffix; for example, course angle S 21° E is 21° east of south, or course 159°.

Course Angle

 

(angle on the bow), the angle between the center line of a vessel and the direction to some object observed from the vessel. It is measured in degrees, which are read on an azimuth from 0° to 180° in the starboard (right) or port (left) direction from the bow of the vessel. With a direction finder the circular system of reading is used (0° to 360°). The direction perpendicular to the vessel’s center line, that is, the one corresponding to a course angle of 90°, is called abeam (port or starboard).

Some of the parameters were fed automatically from sensors: vehicle speed and course angle, angular velocity of the target in the azimuth channel, vehicle roll, distance to the target.
This enables to take the following factors into account: CV speed, roll and trim difference, target relative angular speed, distance to target, type of ammunition, CV course angle, air temperature and pressure, charge temperature, angle of sight, etc.
It is obvious that with the helical motion the course angle [phi] will change over wide limits, since AUV can complete several turnings around the vertical axis.
There are several interesting course angles in the 5.
Adrienne was there with her handheld computer screen and wand, moving around like an artist with brush and palette, all the time relaying to Ricko course angles and the time to the next tack.
