Autonomous navigation and attitude control of spacecrafts on near-earth circular orbits
Abstract
The paper reviews existing methods of spacecraft navigation and attitude control on near-earth orbits, including the methods utilizing earth-based external trajectory measurement stations, global navigation satellite systems, inertial on-board navigation systems and star trackers. The proposed method is based on the obtaining and processing of a set of sky images on-board of a spacecraft that is moving along a near-earth circular orbit. Image processing results are used to fi nd the coordinates, velocity and attitude of a spacecraft in inertial space.
