Abstract
A navigation method includes imaging a first celestial object with an imaging device and calibrating the pointing of the imaging device to position of the first celestial object in the image. A second celestial object and a satellite are imaged and position of the platform determined using position of the conjunction of the second celestial object and the satellite in the image of the second celestial object and satellite. Navigation systems are also described.
