About These Units
Arcsecond (″)
An arcsecond (″) is 1/60 of an arcminute or 1/3600 of a degree. Arcseconds measure stellar positions, telescope resolution, and atmospheric seeing. The Hubble Space Telescope resolves about 0.05 arcseconds. GPS accuracy is measured in arcseconds.
Compass Point (point)
A compass point is 1/32 of a circle or 11.25°. The 32-point compass includes cardinal (N, E, S, W), intercardinal (NE, SE, SW, NW), and secondary-intercardinal points. Traditional maritime navigation uses compass points. "Boxing the compass" means naming all 32 points in order.
