Independent control of geodetic networks above long tunnels by means of astronomically determined azimuths

1997
The work presents the automated astronomical method of determining azimuth and grid azimuth toward to some object on the surface of the Earth. The accuracy of astronomical azimuth determination by observing Polaris with electronic thedolite Kern E2 and Leica T3000 amounts to ą0.4". Such high accuracy in grid azimuth determination enables the control in

Error Analysis Of Clock Time (T), Declination (*) And Latitude (Φ) On Astronomic Azimuth In Minna, Using Sun Altitude And Hour Angle Methods

Journal of Research in National Development, 2008
The major end results of field and geodetic astronomy in surveying include time (t), latitude (Φ), longitude (λ) and azimuth (A); which are aimed at establishing fixed positions and orientations of survey points and lines on the earth surface. The paper attempts the analysis of the individual and combined effects of error in time (t), declination (δ ...

Method of simultaneous determination of astronomic latitude, azimuth and longitude by observing only time and horizontal angles between a pair of stars near elongation and a south star near meridian

Bulletin Géodésique, 1977
This paper endeavours to evolve a method of simultaneous determination of astronomic latitude, azimuth and longitude from observations of a star-pair near their times of east and west elongations and a south star near its time of meridian transit. The star-pair of observation being within a short distance of elongation, either east or west, their ...

Astronomical Aspects of the Rock Sanctuary near the Popovo Lake, Pirin Mauntain and Potential Vectors for Azimuthal Observations of the Sun in Prehistory

2023
Докладът изследва пространствената и времева организация на светилището на брега на Попово езеро в Пирин. Представени са основни аспекти от легендарния материал и от проведените изследвания. На тази база се издига археоастрономическа хипотеза за слънчевите изгреви по време на зимното слънцестоене през специфични точки на релефа на върховете на циркуса ...
