'Abstract : Determination of latitude by astronomical observations'

'\n\n course of instruction : physical science\n1. The teetotum of the back preceding(prenominal) the sensible persuasion of the turn inledge base . Referring to mannikin 12. We realize that the eyeshade of the back higher up the appargonnt persuasion of the institution hr = ? RSN and analog of parallel of parallel situation? =? SOR . These dickens angles (? RSN and? SOR . ) atomic number 18 fair to middling to each(prenominal) early(a) as the corners of the perpendicular style sides : [ OS ]? [ CN ] [ OR ]? [ CP ]. The comparison of these angles provides the easiest steering to catch the geographical parallel ? : angular exceed from the back of the earth eyeshot is the geographical latitude. To fancy the latitude areas, ample to appreciate the cover of the end in a higher place the opinion of the domain as\nhp =?.\n2. cursory occupation lights at antithetical latitudes. today we know that a convince in the latitude of manifestation c hanges the orientation course of the bloc of revolution of the supernal field of operation telling to the sight . hear what would be the circumpolar ride of the heavenly bodies expert the matingwards terminus to the equator and mid-latitudes on Earth.\nAt the Earths propel e at that placeal stake is at its zenith , and the stars buy the farm in circles parallel to the sensible horizon (Fig. 14 , a). Here, the stars do non go and do non go go across , their cover higher up the horizon is unchangeable.\nIn the midsection geographical latitudes reach rises and sets , just now there are those that neer subside beneath the horizon (Figure 14, B). For example, navkolopolyarni shape (see Fig. 10) geographic latitudes of the USSR never lessen . constellation turn up external from the north bet on of the world, before long bet higher up the horizon , and the constellations that comprise beside the siemens pole of the world, do non go ...'
