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).

Subscripts M and T represent the related physical quantities of UAV and target, where r refers to the relative distance between the UAV and target, q refers to LOS (line of sight) angle between UAV and target, [[theta].sub.M] refers to course angle of UAV, [[theta].sub.T] is the course angle of object, [V.sub.M] is the kinematic velocity of UAV, and [V.sub.T] is the kinematic velocity of object.
6 present results of simulations of bringing the ship (1) to the new drilling point situated about 100m on the right above the old one ([y.sub.10] = 0.96, [y.sub.20] = 0.26) with the new course angle [y.sub.30] = [60.sup.0].
where: [C.sub.a]--an aerodynamic coefficient (in most cases could be taken as 1.0 to 1.3); [[rho].sub.1]--air density (for calculation purposes can be taken as 1.25 kg/[m.sup.3]); [S.sub.x]--the space of projection onto a diametrical plane (DP) of the wind surface area of the vessel; [v.sub.a]--wind velocity; [q.sub.a]--wind course angle.
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.
"You can zoom the angle of acceptance in and out so that you can get either fine angle resolution or course angle resolution.
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.
Talk of course angles brings us to Catterick, an established speed track.
The diagram shows the antenna located near midfield on the south side of the runway; the course angles slightly from north to south.
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.
