An apparatus for regulating or controlling a satellite includes: at least one sensor for detecting reference targets such as stars, which is connected to arrangements for selecting and determining the position of reference targets, and to an arrangement for estimating model parameters of the satellite and of external interferences; a memory for storing a reference target catalog and a reference trajectory; a regulating unit for regulating the position of the satellite; and a filter that is connected to the arrangement for position determination of the re...
1. An arrangement for regulating a satellite comprising, on-board the satellite:a sensor adapted to detect stars as reference targets; a selection unit that is adapted to select at least one selected one of the reference targets, and that is connected to said sensor; a position determination unit that is adapted to determine respective positions of the reference targets, and that is connected to said sensor; a parameter identification unit that is adapted to estimate model parameters of at least one model of the satellite and of external interferences ac...
