Abstract:
A system of navigation employing an emergency longitude slide ruler for stellar navigation is described. The emergency longitude slide ruler is equipped with several wheels having rulers with settings including of the longitude slide ruler of the present invention include year, date, hour, minutes, star angle measurement degree wheel, a longitude wheel, a circumpolar star field identifier wheel, star meridian transit angles wheel, and a time zone wheel. All wheels are of diminishing diameters and are laid on top of each other in descending circumference with minute gradations allowing each consecutive wheel to line up with its larger adjacent wheel according to proper settings to eventually indicate longitude. The system presents an efficient and expedient means by which an individual with very limited knowledge of navigation and celestial bodies can determine his or her location, including longitude.

Claim (Index 2):
A method for determining local longitude based on stellar navigation comprising:\n measuring an angle between Polaris and a chosen target start; recording the time; setting a date wheel of a star wheel to the year of the recorded time; setting a time wheel of the star wheel to the date and hour of the recorded time; setting a longitude wheel of the star wheel to the hour, minute, and seconds of the recorded time; setting a circumpolar star wheel to the measure angled using a primary angle arm against a degrees wheel at the recorded time; and adding an azimuth of the chosen star as indicated on a transit star information wheel to a longitude value indicated by the primary angle arm in communication with the circumpolar star wheel.
