  • Navigation system and orientation system incorporating solar sighting
    Patent number: 6043778
    Abstract: A method and apparatus for providing orientation using a solar sighting device. In one embodiment, sighting of the sun and the moon and stars is used to determine orientation. The input from the solar sighting system is input into a processing system along with global positioning system data. Ephemerides stored in the processing system are used in conjunction with time signals from global positioning system data and position determined from global positioning system data so as to determine orientation. This orientation is then used to determine the direction of movement in a vehicle navigation system and is used to orient an optical sighting system.
