Remark 2: The optimal antenna tilt angle [[theta].sup.*.sub.tilt] can be easily obtained by averaging the vertical angles
of the all users.
The distance s in the given horizontal and vertical angles
can be written as
After applying this correction to our data, the vertical angles
of the theodolite fixes did not differ from the GPS positions (Mann Whitney U test, ns).
Images B, C, D and E represent vertical angles
variations at -10[degrees], -20[degrees], -30[degrees] and -40[degrees], respectively.
This issue aside, subtracting the average stray light measurement from the measured data will result in readings for vertical angles
greater than 90[degrees] that may be greater or less than zero.
Difference consists of calibrating the instrument when the instrument itself is positioned in the vertical direction from which horizontal and vertical angles
must be measured.
of the tug ropes made 65 degrees in the fore and 60 degrees in the aft of the ship.
Airplane pilots would achieve more consistent and better results if they focused more on the vertical angles
to the runway and touchdown down point and less on horizontal distances.
The NETH503 5" Theodolite has a 30x telescope with illumination, 360 degree full transit, digital reading of both horizontal and vertical angles
, dual-side LCD display, photoelectric incremental encoder, optical plummet, alkaline or rechargeable battery pack selectable.
Regarding Ian Blair Fries article on angles ("Flying By Vertical Angles
" June 2010 IFR): Many years ago I bought a small telescoping device with a gravity bubble in the sight window, which allows me to accurately gauge my ability to clear the height of clouds and terrain.
An increase in mesial and vertical angles
improved the identification of 2 root apexes and caused less distortion of apical area, making the apex limits easy to identify.
Calibration of the accuracy of vertical angle
measurements by the geodetic instrument is usually performed using a special test bench composed of autocollimators attached at the different vertical angles
to the calibrated instrument (Fig.
