This paper presents a method for autonomous attitude and position (pose) estimation for spacecraft in lunar orbit, which may be used when a spacecraft loses communication with Earth. Using only on-board equipment, namely, a visible camera with the capability of taking multiple pictures featuring the Moon and stars, pose estimation is performed. A set of pictures of the stars will be used to estimate the direction towards the Moon, while a picture of the Moon will be used to estimate the distance between the observer and the Moon. Together, these will provide enough information to estimate inertial position.
