Direction determination refers to the ways in which a cardinal direction or compass point can be determined in navigation and wayfinding.The most direct method is using a compass (magnetic compass or gyrocompass), but indirect methods exist, based on the Sun path (unaided or by using a watch or sundial), the stars, and satellite navigation.

Most sun charts plot azimuth versus altitude throughout the days of the winter solstice and summer solstice, as well as a number of intervening days.Since the apparent movement of the Sun as viewed from Earth is nearly symmetrical about the solstice, plotting dates for one half of the year gives a good approximation for the rest of the year.
Soon Texans will get to see something that rarely happens. The total solar eclipse is set to be seen on April 8, according to NASA.The path of the eclipse will be along a southwest-to-northeast ...
32-point compass rose. The points of the compass are a set of horizontal, radially arrayed compass directions (or azimuths) used in navigation and cartography.A compass rose is primarily composed of four cardinal directions—north, east, south, and west—each separated by 90 degrees, and secondarily divided by four ordinal (intercardinal) directions—northeast, southeast, southwest, and ...
FILE - A solar eclipse is observed over Chile in 2019. A similar eclipse will be visible over many parts of the U.S. on April 8, with Georgians expecting a partial eclipse.
The April 8 solar eclipse will be broadcast live on both network TV and cable channels. NBC will air a two-hour special, "Total Eclipse 2024," at 2 p.m. ET. NBC Nightly News anchor Lester Holt ...
