Sonnenschein, F.J. Institution National Aerospace Laboratory NLR Date 1979-11-15 Abstract The study deals with the rotational motion of a spin-stabilized spacecraft equipped with a V-slit sun sensor and the X-slit ESA starmapper. Assuming complete absence of an a priori attitude estimate, it is required to produce a rough estimate of the spacecraft attitude motion. It was assumed that sensor misalignments, external torques and nutation are negligible. The estimation algorithm is described, together with datails of its software implementation. Simulations using pseudomeasurements (generated by a truth model) were carried out for a number of parameter combinations, including nutation, sensor misalignments, different spin rates, telematry resolution- and spacecraft assymetry. In all simulations the spacecraft attitude could be estimated with errors of no more than about one arcminute. Apparently, the algorithm is robust with respect to parameter variations.
