I'm trying to figure out the necessary azimuth and elevation angles for an antenna located at 42 degrees, 06 minutes N lat, 76 degrees, 13 minutes W long, pointing towards a geosynchonous satellite at ...

The altitude and azimuth instruments made by Edward Troughton in London from the 1790s were remarkably stable and accurate, and Troughton & Simms continued this tradition. Indeed, Frederick W. Simms ...

(1) NAUTICAL astronomy is simply the application of spherical trigonometry to the problem of ascertaining the latitude and longitude at sea by observations of the heavenly bodies; as also the errors ...

We’re past the winter solstice and the days are getting longer, but that doesn’t mean we’re not sick of the sun setting around 5 in the afternoon. There is a way to get more sunlight through our ...

A ±1° change in azimuth displaced the shadow by about 23 centimeters; a ±1° shift in elevation altered it by a full meter. Positional shifts of just 10 centimeters in the sun's origin point caused a ...
