NOMAD

(Naval Observatory Merged Astrometric Dataset)
(astrometric star catalog)

NOMAD (for Naval Observatory Merged Astrometric Dataset) is an astrometric catalog of stars gathered from surveys, with updated position information, produced by the US Navy. It is a follow-on to earlier US Navy efforts, such as USNO-A and USNO-B (USNO is for United States Naval Observatory). Navies and sea-going vessels have a traditional interest in accurate star charts as an aid to navigation.
