Abstract
Disclosed is a system of navigation that is not dependent on man-made satellites. Disclosed is a digital imaging system that may be calibrated using known angular distances and then used to determine unknown angular distances, including the angular distance of celestial bodies above the user's horizon. The digital imaging system may be used in conjunction with a celestial database to determine lines of position and establish a fix revealing the geographic location of the user. The system is expected to be most useful when employed on vessels at sea, including aircraft, and may also be useful on land. The invention offers an alternative to Global Positioning Systems, which are subject to inactivation by governments or traditional mechanical-optical sextants, which are time consuming and cumbersome to use.
