Astronomer's measurements

Usage examples of azimuths.

The electronic surveillance package on board the helicopter received and processed the signals using the targeted frequencies and recorded that information in its computer as back azimuths, or lines leading from the helicopter back in the direction from which the signals originated.

After several seconds, this computer had accumulated several back azimuths, since the helicopter was moving and the source of the signal was not.

Using its own internal mapping system, the computer plotted all the back azimuths and compared them.

The point where all the back azimuths came together gave it, and everyone who had access to the computer's data down-link, the precise location of where the signals originated.

When I give the numbers to Bobby, I should have a straight line running through the sky from just north of west to just south of east, and even with the crude measurements of the protractor, should be able to give him a reasonable close approximation of times and azimuths.

From the GPS receiver, I'd worked out precise locations of the three satellite dishes we'd seen, and the distances between them, and also gave him the directions, azimuths, and times I'd taken from the dish.

While the dish is moving, make the same kinds of notations you did the other night—direction, times, and azimuths.

I, with my smug superiority and my cheap little bag of tricks like spherical trigonometry and azimuths and sun lines and hour angles and bearings from fixed points, having the effrontery to say a man was crazy because he thought he could go back and find something he'd lost in an ocean.

The unit had been on support duty in Fort Monmoth for so long they weren't in any way, shape or form prepared to do anything but fire, from exactly the same positions, on the same azimuths and elevations, day after day.

He gave a fourth man a compass and sent him up a tree to give him azimuths and range estimates as needed.

He reviewed all the figures of the survey, including the Floozie and Doll figures, spoke with the military experts about corrected azimuths and trigonometric functions-which made Dor nervous.

He used a compass to shoot azimuths from three landmarks around the narrow, steep-sided gorge they were in, then marked the position he calculated on the overlay and wrote down the coordinates.
