Corrections of Maximum and Ex-Meridian Altitudes

Naturevolume 51pages485486 (1895) | Download Citation



IN navigation the error introduced by taking the maximum altitude of a heavenly body for its meridian altitude is not sufficiently great to need correction when it is due to variation of declination alone, as it is then much within the probable errors of observation. When, however, a ship is steaming at a highspeed, the error is considerably increased by the variation of latitude, especially when this is of opposite sign to the variation of declination.
