Abstract
A method and system for celestial navigation are provided. The method comprises requesting access to a light source on a low earth orbit (LEO) satellite; and sending an uplink message to the LEO satellite to power on the light source, in response to the access request. The method further comprises determining whether the LEO satellite is in view of a camera; capturing a light image, from the light source, on a focal plane location of the camera when the LEO satellite is in view of the camera; and comparing the focal plane location to a predicted location of the LEO satellite. The method updates position information of a user based on an observation error from comparing the focal plane location to the predicted location.
