UrukFSP is a free, cross-platform software designed for archaeoastronomy, planetarium simulation, and eclipse research.
Features
UrukFSP offers a wide range of features to assist users in studying astronomical events past, present, and future. Some of its key features include:
- Advanced sky simulations: UrukFSP allows users to simulate the appearance of the sky in the range of ± 100.000 years from the present epoch (stars) and from -13000 to +17000 (sun and planets). This is useful for studying the visibility of celestial objects such as stars, planets, and moons on specific dates.
- Astronomical event search: UrukFSP can be used to find a variety of astronomical events, including eclipses,conjunctions, occultations, and transits. Users can specify search criteria such as date, time, and location to find events of interest.
- Visualization of astronomical events: UrukFSP can generate diagrams and ephemerides to visualize astronomical events. This can help users better understand the geometry and timing of events.
- Tools for archaeoastronomy: UrukFSP includes specific tools for archaeoastronomy, such as the ability to align ancient monuments with celestial objects. This can help archaeologists better understand the orientation and meaning of these sites.
Supported Platforms
UrukFSP is a cross-platform software available for the following operating systems:
- macOS: Catalina, Big Sur, Monterey, Ventura, Sonoma, M1, M2, M3
- Linux (64 bit)
- Windows (64 bit)
Development
UrukFSP is written in Free Pascal 3.2.2 using the Lazarus 3.6 IDE (Lazarus 3.7 MacOS).
Target Users
UrukFSP is designed for a variety of users, including:
- Astronomers: UrukFSP is a valuable tool for astronomers who study past, present, and future celestial events.
- Historians: UrukFSP can be used by historians to search for correlations between historical and astronomical events.
- Archaeologists: UrukFSP includes specific tools for archaeoastronomy that can help archaeologists better understand ancient sites.
- Educators: UrukFSP can be used to teach astronomy and archaeoastronomy to students of all ages.
- Hobbyists: UrukFSP is a valuable tool for anyone interested in astronomy and archaeoastronomy.
