SOFA (Standards of Fundamental Astronomy)

The SOFA (Standards of Fundamental Astronomy) is a comprehensive set of internationally recognized, precise mathematical algorithms and data used by astronomers to calculate positions, motions, and timings of celestial objects and events. It ensures consistency and accuracy in astronomical measurements worldwide, supporting tasks like navigation, space missions, and observing star positions. Think of it as a standardized toolbox that ensures everyone’s calculations align, enabling reliable and unified understanding of the universe's fundamental celestial phenomena.
