One nautical mile is one minute of astronomical latitude.

:This source indicates that observations with broken telescopes, such as the Wild T-4, could determine latitude and longitude accurtely enough to detect the diference between geodetic and astronomical latitude and longitude, which is related to deflection of the vertical.

Astronomical latitude is not to be confused with declination, the coordinate astronomers use in a similar way to specify the angular position of stars north / south of the celestial equator ( see equatorial coordinates ), nor with ecliptic latitude, the coordinate that astronomers use to specify the angular position of stars north / south of the ecliptic ( see ecliptic coordinates ).
