The paper examines the features of an autonomous navigation technique based on the optical sighting of inhomogeneous regions on the planetary surface and regions of the starry sky near the horizon. An image analysis made it possible to identify landmarks on the planetary surface as well as reference stars, to determine the direction of the lines of sight of the landmarks in an inertial coordinate system as well as star heights above the horizon of the planet, and to define the spacecraft orbital elements. The navigation precision is investigated.
