Welcome to the Humans of Dawn Project! The idea for this project was born to the begining of the new Millennium. The AstroArch development as part of the project was started autumn 2017 and the first working development version was finished in February 2018. Since beginning 2020 the tool is available for download as freeware.

About the Author

Ivan Krastev successfully completed his education as a physicist at the University St. Kliment Ohridski of Sofia, Bulgaria (1989). His master's thesis is in the field of optics and spectroscopy. He lives in Austria, Moedling near Vienna since 1991 and has been working as a software developer in the IT industry for over 25 years. Ivan is the developer of MODAS (Modern Optical Design and Analysis Software), popular worldwide among amateur astronomers and telescope makers. From 2003 to 2012 Ivan was owner and editor of the journal ATMLJ (Amateur Telescope Maker Letters Journal) and for almost 10 years successfully reported to hundreds of readers worldwide on topics such as classic optics, optical calculations and design, astronomical calculations, history of optics, astronomy, sundials and antique telescopes. AstroArch is his latest software development.

Tools: AstroArch freeware

AstroArch is a tool for archaeoastronomical research, using the latest technologies in the field of Geographic Information Systems (GIS), Shuttle Radar Topography Mission (SRTM) and precise astronomical calculations based on Variations Seculaires des Orbites Planetaires (VSOP87). The author has successfully developed a unique software in the field of archĐ°eoastronomy. He has managed to bring the most important tools for calculating and analyzing prehistoric data under one roof. The program developed by him with intuitive user interface and operation brings the user the most important tools for analysis, such as realistic horizon profiles with impressive display depth and short calculation time, without the use of 3D techniques, generating relief maps with various color palettes, representation of the most important astronomical events, such as rising/setting of celestial bodies (sun, moon, planets, stars), ephemeris calculations, as well as orientation's diagrams and histograms.

Tools: AstroArch SDK

Irrespective of AstroArch program, an archaeoastronomical software development kit (SDK) consisting of a few DLLs with associated wrapper for Delphi, Visual Basic, C #, C ++ and extensive application examples will be developed. This will enable users to develop their own archaeoastronomical tools and realize their own ideas.

coming soon...
