Patent ID: 8837782

Claim:
A method for geoposition determination of longitude and latitude of a camera on a movable platform in the presence of at least one Earth satellite and first and second stars, said method comprising the steps of: obtaining, using the camera, a first image including the at least one earth satellite and the first and second stars; determining x and y positions of the at least one earth satellite and the first and second stars in the first image; and in a computer process, determining, from said determined x and y positions of said at least one earth satellite and said two stars-in said first image, a first set of possible locations of the camera in three-dimensional space, wherein said set of possible locations of the camera in three-dimensional space is determined by creating a curve mapped on a surface of the Earth, based on vectors measured in the first image from the camera to the first star, from the camera to the second star and from the camera to the at least one earth satellite.
