海军天文台矢量天体测量软件（NOVAS）是一个免费的源代码库，用于计算位置天文学中各种常用的量。NOVAS可以在一个或两个子程序或函数调用中提供任何恒星或行星在各种坐标系中的瞬时天体位置。NOVAS还提供了进入此类计算的所有“构建块”的访问-通用天体测量算法的单一用途子程序或函数，例如旋进，章动，像差，视差等。NOVAS的计算精确到亚毫弧秒级别。NOVAS包是一个易于使用的设备，可以集成到数据简化程序、望远镜控制系统和模拟中。NOVAS用于制作美国部分的《天文年鉴》。
The Naval Observatory Vector Astrometry Software (NOVAS) is a free source-code library for computing various commonly needed quantities in positional astronomy. NOVAS can supply, in one or two subroutine or function calls, the instantaneous celestial position of any star or planet in a variety of coordinate systems. NOVAS also provides access to all of the “building blocks” that go into such computations—single-purpose subroutines or functions for common astrometric algorithms, such as those for precession, nutation, aberration, parallax, etc. NOVAS calculations are accurate at the sub-milliarcsecond level. The NOVAS package is an easy-to-use facility that can be incorporated into data reduction programs, telescope control systems, and simulations. NOVAS is used in the production of the U.S. parts ofThe Astronomical Almanac.
