The initial course angle
is 0[degrees], and the desired course angle
They are able of measuring course angle
on target (that is ionizing radiation source) with the accuracy of 13 degrees .
The command course angle
is set to be -30[degrees] and 60[degrees], respectively, to verify the proposed control design.
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
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.
