Variables like weather, azimuth, elevation, crude launchers, and rocket viability quickly add up.
Then the azimuth is represented unaltered, and any spherical distance z is represented by ρ.
To find an azimuth of the sun: Note the time of taking the azimuth by chronometer.
Bivalve apparatus; panels of 147 in azimuth and 122 vertical angle; mercury rotation.
At the same time, get your true bearing of the sun from the azimuth Tables.
The angle which this line makes with a line pointing due south is called the sun's azimuth.
These were the chronometer and the azimuth compass of the Bounty.
Its operation was very much as if his mural quadrant could be swung round in azimuth.
Observations for azimuth were always taken to the sun before and after noon.
What is the object of the travel-devices for range and azimuth correction on the gun-arm?
The position of a celestial object along an observer's horizon. Azimuth is a horizontal angle measured clockwise in degrees from a reference direction, usually the north or south point of the horizon, to the point on the horizon intersected by the object's line of altitude (a line from the observer's zenith through the object to the horizon). If north is the reference point (0°), then east has an azimuth of 90°, south is 180°, and so forth through 360°. See more at altazimuth coordinate system.
