The Naval Observatory Vector Astrometry Subroutines (NOVAS) is a software library developed by the U.S. Naval Observatory (USNO) to provide precise astronomical calculations related to the position and motion of celestial objects. It is particularly focused on vector astrometry, which involves the use of vectors to describe and compute the positions and movements of stars, planets, and other celestial bodies in various coordinate systems.
