Abstract: The problem of refining the parameters of the mutual attitude of the onboard imaging camera and the star tracker installed on the orbiting spacecraft is considered. A distinctive feature of the problem statement and the solution is that the refinement is based on observations of landmarks that are not georeferenced and no GPS messages are used.
